Improvements in a 3D target shooting training glasses and target. The 3D target, shooting glasses and training system that allows starting shooters and experienced shooters to improve their skills and accuracy. The paper targets are printed with offset colors that create a 3D image when viewed through 3D glasses. The offset is typically filtered for a red color and a blue color to provide a depth to the image. Shooting glasses are used with each lens providing a color filter to allow a 3D printed target depth perception and sighting training through a dominant eye. The 3D target shooting training glasses and target to provide a training system that allows a user to identify a dominant eye and use the glasses and 3D printed image to aim using the dominant eye on the target while maintaining peripheral vision.

Methods and apparatus to calibrate and/or validate stereoscopic depth sensing systems are disclosed. An example apparatus includes an image generator to generate a first image for a first image sensor; and generate a second image for a second image sensor. First content in the first image is to be shifted relative to corresponding second content in the second image by a shift amount. The shift amount based on a target depth to be tested. The example apparatus further includes a calibration controller to cause the first and second images to be presented on the display screen; and calibrate the first and second image sensors based on a difference between the target depth and a measured depth. The measured depth based on an analysis of the first and second images as captured by the first and second image sensors when the first and second images are presented on the display screen.

Provided are stereoscopic eyeglasses capable of reducing visual fatigue in binocular stereoscopic display by a simple configuration. In stereoscopic eyeglasses, in order to expand a tolerance of match between vergence and accommodation enabling comfortable stereovision in eyeglasses-using stereoscopic display, wide-focus lenses ranging in focal length are incorporated so as to overlap optical filters in light transmission directions, and accordingly, visual fatigue to be caused by vergence-accommodation conflict during stereoscopic image observation is reduced.

Systems and methods for auto-calibrating a virtual reality (VR) or augmented reality (AR) head-mounted display to a given user with a refractive condition without adding corrective lenses to optical elements of the head-mounted display and without requiring subjective refraction procedures. An autorefractor assembly of the head-mounted display, or a separate autorefractor headset, measures refractive error and communicates the measurements to a control system of the head-mounted display. Based on the refractive error measurements, the head-mounted display can adjust adaptive lenses and other adaptive optics to modify transmitted images; can make compensating adjustments to images displayed by a stereoscopic display device of the head-mounted display; or can make both types of adjustment. These automatic calibrations correct displayed images to compensate for refractive aberration in one or both eyes of the user. In an embodiment, the head-mounted display can correct other vision defects of the given user measured by objective ophthalmic examination.

Some implementations of the disclosure are directed to tessellating a light field into a size or depth that is larger or further extended than the pupil size of an imaging system or display system. In some implementations, a display system comprises: a display configured to emit light corresponding to an image; a first optical component positioned in front of the display, the first optical component configured to pass the light to an orthogonal field evolving cavity (OFEC) at a plurality of different angles; the OFEC, wherein the OFEC comprises a plurality of reflectors that are configured to reflect the light passed at the plurality of different angles to tessellate the size of the image to form a tessellated image; and a second optical component optically coupled to the OFEC, the second optical component configured to relay the tessellated image through an exit pupil of the display system.

There is provided an electro-optical apparatus including an element substrate that includes a display region in which a plurality of pixels, which are light-emitting elements, are arranged in a matrix form. The light-emitting element has a structure in which a reflective electrode, a protective layer, an optical path adjustment layer, a first electrode, a light-emitting layer, and a second electrode are laminated on an insulation layer. The reflective electrode is disposed by being split in each pixel, and a gap is formed between each reflective electrode that is disposed by being split in each pixel. The protective layer covers the surface of the reflective electrode on which the gap is formed, and includes an embedded insulation film which is embedded in the gap.
