DEVICE FOR PRODUCTION OF STEREOSCOPIC PICTURE OF OBJECTS Russian patent published in 2004 - IPC

FIELD: production of stereoscopic picture of objects. SUBSTANCE: the device a picture source (1) in the form of a single two-dimensional object and an optical lens raster (2), whose lenses (5) have a focal power in the sagittal and meridional sections. Raster (2) in the sagittal and/or meridional sections has lenses with similar focal distance f, whose main planes (7) are located from the plane of picture source (3) at distances: from 0.5 f to f, f, and from f to 1.5f. The raster lenses in the mentioned sections are separated by intervals 6 with a zero focal power. EFFECT: provided production of a stereoscopic picture with a prescreen output, increase of the postscreen perspective to a virtual infinity, as well as expansion of process potentialities in manufacture of the device. 5 dwg
