OPTICAL SYSTEM OF STEREOSCOPIC CAMERA Russian patent published in 1995 - IPC

FIELD: optical instrument engineering. SUBSTANCE: optical units are disposed in stereoscopic camera between objectives and gate masks. The units shift image away from axis of objective. Reflectors of the objectives are movable and shift identically at two adjacent units. The shift is used for achieving complete overlap of frames at different focusings, as a result, stereoscopic effect is reached through all the area of the frame. To eliminate parasitic exposure, two-wedge units are disposed between the reflectors, the units may be integrated with reflectors which are made in form of right-angle prisms. EFFECT: improved comfort; improved efficiency. 6 cl, 5 dwg
