An autostereoscopic display screen includes a light-deflecting component and a double-sided lenticular lens. The light-deflecting component is configured to deflect a light beam towards multiple directions. The double-sided lenticular lens includes a first cylindrical lens array, a second cylindrical lens array, and a central portion. The first cylindrical lens array includes first cylindrical lenses, in which each of the first cylindrical lenses has a first length in a first axial direction. The second cylindrical lens array includes second cylindrical lenses and at least one third cylindrical lens. The second cylindrical lenses have a second length in the first axial direction and the third cylindrical lens has a third length in the first axial direction, in which the first length is greater than the second length and the second length is greater than the third length. The central portion is disposed between the first and second cylindrical lens arrays.

This invention teaches a binocular telescope wherein wedge prisms are positioned in the optical path of each telescope to control the amount of perceived parallax between the left and the right images. In one embodiment, a pair of thin wedge prisms are positioned in front of the objective lenses to optically manipulate the real convergence angle of an object viewed through the binocular telescope. In a second embodiment, wedge prisms are positioned after the eyepiece lenses to manipulate the apparent convergence angle of an object viewed through the binocular telescope. Depending on the position and the orientation of the wedge prisms, the invention produces benefits such as better depth perception, increased field of view, and the possibility to view close objects.

A light device includes a transparent substrate having a first surface and a second opposite surface, an array of light-modifying elements formed on the substrate, and a light source to project light along a thickness direction of the substrate. The light-modifying elements having surfaces inclined at an angle with respect to at least one of the first surface and the second surface, and configured to diffuse light by reflecting and/or refracting incident light.

A display method of an image is disclosed. A position of a vergence surface of a user is obtained through a gaze tracking device.
