Optical systems or apparatus for producing three-dimensional [3D] effects, e.g. stereoscopic images > by providing first and second parallax images to an observer’s left and right eyes > of the stereoscopic type

CPC:

Optical systems or apparatus for producing three-dimensional [3D] effects, e.g. stereoscopic images (in microscopes G02B21/22) > by providing first and second parallax images to an observer's left and right eyes > of the stereoscopic type

Additional Content IPC

Stereoscopic with left and right images projected to the left and right eyes of an observer, who is required to view the image through an optical system placed adjacent to the eyes.
