APPARATUS FOR RECEIVING STEREOIMAGE Russian patent published in 1995 - IPC

FIELD: photographic technology. SUBSTANCE: apparatus has a housing, having in its front wall two input ports, through which light beams from an object, being filmed, fall on refracting surfaces of left and right outer movable prisms, then reflect from refracting surfaces of left and right inner stationary prisms, mounted on a central prismatic strut, pass through an output port and through an objective lens of a camera, fall on photofilm. The apparatus allows to perform a stereo movie filming of an object with variable (in accordance with its remoteness) convergence angle. Elimination of physical rotation axles of members of an optical system allows to decrease vertical dimensions of the apparatus and also to minimize errors at filming, being caused by clearances in the rotation system of members of the optical systems. The apparatus may be used with any vertical-type camera. EFFECT: enlarged using range. 1 cl, 1 dwg
