Multiple microlens focal planes align accommodation with vergence in AR/VR displays, improving depth perception and reducing dizziness.
Foldable support legs and a deployable mirror turn a smartphone case into an affordable hands-free magnifier for nearby reading and distant viewing.
Three-lens optics with adjacent Fresnel surfaces expand head-mounted display FOV beyond 100° while shortening optical length and limiting stray light.
An integrated camera in the lamp head enables image capture, adjustable viewing, and easy sharing of inspected objects to external devices.
A thicker HMD display cover plate shifts dust images out of focus, hiding black spots and lines without major size increase.
A three-lens polarized pancake layout cuts ocular weight and size while preserving image quality, field of view, and manufacturability.
A spectroscope merges main and auxiliary optical paths to deliver clearer, lower-distortion HMD imaging in a lighter eyepiece.
