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

FIELD: production of stereoscopic picture of objects. SUBSTANCE: has a source of picture (1) in the form of a single two-dimensional object and optical lens raster (2). The picture source (1) is located in the plane preset by the focal distance of lenses (4), having the maximum value of focal distance f_max in the meridional section, and the plane present by the focal distances of the lenses having the minimum value of focal distance f_min in the meridional section, is located between raster (2) and picture source (1). The value of focal distance f_min should be within f1min

≤f_min≤f2min, where ; P - the dimension of the raster diagonal; L-the distance of the best vision of the spectator's eye. EFFECT: provided production of a stereoscopic picture of the object with a prescreen output, as well as an increased of the postscreen perspective to a virtual infinity. 2 dwg
