Exploiting the interplay between gain, loss and the coupling strength between different optical components creates a variety of new opportunities in photonics to generate, control and transmit light. Inspired by the discovery of real eigenfrequencies for non-Hermitian Hamiltonians obeying parity–time (PT) symmetry, many counterintuitive aspects are being explored, particularly close to the associated degeneracies also known as ‘exceptional points’. This Review explains the underlying physical principles and discusses the progress in the experimental investigation of PT-symmetric photonic systems. We highlight the role of PT symmetry and non-Hermitian dynamics for synthesizing and controlling the flow of light in optical structures and provide a roadmap for future studies and potential applications. This Review discusses recent developments in the area of non-Hermitian physics, and more specifically the special case of non-Hermitian optical systems with parity–time symmetry.
Fig. 8 is a plan view of one embodiment of a light redirection structure comprising an array of the steerable light collimators of Fig. 7;--
Micro-LED displays have been proposed as replacements for the above-noted SLM displays and scanning-fiber displays. Micro-LED displays have various advantages for use in HMDs. As an example, micro-LED displays are emissive. The power consumption of emissive micro-LED displays generally varies with image content, such that dim or sparse content requires less power to display. Since AR and MR environments may often be sparse — since it may generally be desirable for the user to be able to see their surrounding environment — emissive micro-LED displays may have an average power consumption below that of other display technologies that use an SLM to modulate light from a light source. In contrast, other display technologies may utilize substantial power even for dim, sparse, or “all-off” virtual content. As another example, emissive micro-LED displays may offer an exceptionally high frame-rate (which may enable the use of a partial-resolution array) and may provide low levels of visually apparent motion artifacts (for example, motion blur). As another example, emissive micro-LED displays may not require polarization optics of the type required by LCoS displays. Thus, emissive micro-LED displays may avoid the optical losses present in polarization optics.
[09] Many micro-LED displays may include planar light emitters formed on a substrate, whereas other micro-LED displays may include nano-wire LEDs formed of arrays of vertically extending nanowires (for example, spaced-apart pillars of material) electrically connected to two electrodes, and that emit light upon application of current through the nanowires, as described in U.S. Patent No. 11 ,604,354, which is expressly incorporated herein by reference.
Because each LED in the micro-LED display may emit light with a larger than desired angular emission profile, such that only a small portion of the emitted light may ultimately be incident on the eyepiece, thereby wasting light. In some embodiments, light collimators (e.g., micro-lenses, nano-lenses, reflective wells, metasurfaces, and liquid crystal gratings) may be utilized to narrow the angular emission profile of light emitted by the LEDs in a micro-LED display. The light collimators are preferably positioned directly adjacent or contacting the LEDs to capture a large proportion of the light emitted by the associated LEDs.
DISPLAY DEVICE WITH DARK RING ILLUMINATION OF LENSLET ARRAYS FOR VR AND AR - US20230386373
[...]
One step further eliminates the duplicate information in the display. As is disclosed in PCT11 this strategy permits an increased focal length, which in turn results in an increased resolution.
However, a longer focal length also leads to a larger device which may be undesirable. In an alternative configuration, the lenses in the array are split into families and the focal length reduced, reducing device size.
Each family now generates a lower resolution virtual image, but said virtual images generated by the different families are interlaced to recover a high resolution.
These configurations combine the compactness of short focal devices with high image resolution.
However, these configurations don't make a full use of the panel because some panel pixels (also called object pixels) need to be turned off to avoid crosstalk between channels and consequently cannot be used to send images to the eye. This crosstalk occurs because each channel is designed to create on the eye retina a partial virtual image from the light coming from a particular set of object pixels (called cluster), and so, the light coming from pixels not belonging to its cluster and processed by the channel may create unwanted overlapped images. This is particularly dangerous for the pixels that are physically close to the cluster. Light from pixels far from the cluster may illuminate the channel, but the channel redirects it far from the eye pupil so that light does not get into the eye and does not creates crosstalk, in general.
A step further to make full use of the panel is disclosed herein.
This step consist of confining the emission of the panel pixels so the light emanating from them does not illuminate channels close to the right one. This eliminates the need of turning off some object pixels, allowing for a full use of the panel. This strategy not only improves the effective use of all panel pixels but also reduces the power consumed by reducing the light emitted outside the eye pupil.
Additionally, as disclosed herein, this strategy allows also color images without the use of absorbing filters, improving energy efficiency and cost a bit further. Optionally, color sequential can be used (which leads to improvements in virtual image resolution) if the panel switching speed.
The present disclosure relates to Extended Reality "XR" devices. More particularly the disclosure relates to HeadMountedDisplay Device "HMD" such as Extended Reality "XR" devices for motion synchronization-based head pose estimation, and method thereof.

Finally, the method includes synchronizing the image frames received from the SLAM camera and the filtered subset of the motion data and estimating the head pose based on the synchronized image frames and motion data.
US20240295751 - WEARABLE DEVICE WITH A CORRECTIVE LENS HAVING A DIFFRACTIVE SURFACE
***
Prescription in smartglasses if a typical hurdle to be effectively included in the glasses, quite a common problem.
This patent offers an alternative interesting concept. Beign diffractive, the idea sees a good production potentiality.
***
In the realm of Augmented Reality "AR" or Virtual Reality "VR" HMD devices have the capability to perform various tasks such as object interaction, drawing in AR, and navigation. However, to navigate in the AR or VR, HMD devices require an efficient method of Simultaneous Localization and Mapping "SLAM" which involves establishing a connection or mapping the user with respect to three-dimensional "3D" space. Inertial Measurement Unit "IMU" sensors provide data at a higher frequency than the rate at which images are provided by the camera sensor. Current SLAM methods use IMU data for initial head movement prediction, and visual cues to refine the predicted movement using Bundle Adjustment, "BA", ultimately outputting the refined pose as the final head pose.

US20240364841 - Representing Real-World Objects with a Virtual Reality
EnvironmentAn image processing system can provide a virtual reality (VR) experience to a user wearing a head-mounted display (HMD) and can enable the user to interact with one or more objects in a real-world environment. In one example, the image processing system receives image data (e.g., one or more still frame images and/or video frame images, etc.) of a scene. In some cases, receiving data can include capturing, detecting, acquiring, and/or obtaining data. The scene can be associated with a real-world environment around the user wearing the HMD. The real-world environment can include a real-world object that is captured in the scene. In other words, received image data representing the scene can include image data that represents the real-world object. The real-world object in the captured scene (i.e., in the received image data of the scene) is referred to as a target object. In this example, the user wearing the HMD and experiencing a virtual environment may desire or intend to interact with the target object while continuing to experience the virtual environment while wearing the HMD. The image processing system can detect or identify the target object in the captured scene. After identifying the target object in the captured image, the image processing system can include the target object within the virtual environment that the user is experiencing via the HMD. A generated scene including the virtual environment and a rendering (i.e., a rendered/generated representation) of the target object is referred to as a combined scene. The image processing system can present the combined scene to the user via the HMD.
In some embodiments, the image processing system creates the appearance that the target object (e.g., received pixel data representing the target object) “passes through” into the virtual environment provided to the user via the HMD. A user holding a target object, for example, may have the target object represented in the virtual world shown in the HMD at the location of the physical object in the real world. For instance, pixel data received for the target object (e.g., real-world object) can be used to generate pixel data for a representation of the target object rendered in combination with the virtual environment. The pixel data for the representation of the target object can be rendered in a combined scene with the virtual environment. In some cases, the pixel data received for the target object can be modified in order to generate the pixel data for the representation of the target object rendered in combination with the virtual environment. In some cases, the pixel data for the representation of the target object can be generated to be equivalent to the pixel data initially received for the target object.
Moreover, in some implementations, the image processing system can cause the target object to appear to be overlaid on the virtual environment experienced by the user wearing the HMD. In some implementations, while rendering the target object with the virtual environment, the image processing system can apply a graphical overlay, such as a skin, to the target object. The graphical overlay can, as used herein, refer to a visual effect that the image processing system applies in association with rendering a representation of the real-world object. In some cases, the graphical overlay (e.g., skin) can be applied in attempt to assist the user to track the target object in the virtual environment, and/or to allow the target object to more appropriately fit the virtual environment in a graphical sense (e.g., to visually fit a theme of the virtual environment).
- DGIST Professor Youngu Lee and Jeonbuk National University Professor Jaehyuk Lim successfully developed an ultra-sensitive, transparent, and flexible electronic skin mimicking the neural network in the human brain. - Applicable across different areas, including healthcare wearable devices and transparent display touch panels.
An antenna of the radar sub-system may be positioned downward from a head of a user and at a predefined angle to detect the gesture while the user is in a natural pose.

Slanted surface relief gratings for use in an optical display system in an HMD device are replicated in a manufacturing process that utilizes non-contact optical proximity recording into a specialized photo-sensitive resin that is disposed over a waveguide substrate. The recording process comprises selective resin exposure to ultraviolet light through a mask to spatially record grating structures by interferential exposure and polymerization. Subsequent resin development evacuates unexposed resin down to the waveguide substrate to remove flat surfaces, referred to as a bias layer, that remain in the grating trenches after exposure. The resin development reduces Fresnel reflections that could otherwise be induced at the media interface between the bias layer and the waveguide substrate. Fresnel reflections may cause a loss of diffraction efficiency and thereby reduce the field of view that may be guided by the SRGs in the optical display system.

In virtual environments such as, for example, the metaverse, users can represent themselves as avatars. A user may use head-mounted displays (HMDs) as portals to the virtual environment. HMDs include virtual reality (VR), augmented reality (AR), and/or mixed reality (MR) devices including headsets, goggles, glasses, etc. With HMDs, the location of the eyes of the user wearing the HMD relative to cameras and other sensors in the HMD is predictable. Thus, the user's avatar appears naturally oriented in the virtual environment.
[0016] In addition to HMDs, other electronic devices may be used as portals for virtual environments. For example, a personal computer (PC) may be used as a metaverse portal, alternatively or in addition to HMDs. With some PC setups, such as for example laptop computers with external
d isplays and/or multi-display desktop computers, the location of the camera and/or other sensors may be offset from the display of the virtual environment. For example, FIG. 1 shows an example laptop computer 102 with an example camera 104 positioned adjacent to an example external display 106. An example virtual environment 108 is presented on the external display 106. An example avatar 110 of an example user 112 is presented in the virtual environment 108. The position or orientation of the avatar 110 is determined based on data gathered by the camera 104.
