ABSTRACT:
A photographic camera for three dimensional photography. The photosensitive material is positioned at a fixed location during the exposure cycle of the camera. Optics projects the light from a scene to be photographed along an optical path onto the located photosensitive material. A lenticular screen is positioned in the optical path and adjacent the location for photosensitive material. The path of light from the scene is blocked and an optical aperture is passed across the optical path for sequentially exposing the photosensitive material through the lenticular screen to the light rays from the scene. A lenticular screen is moved a predetermined distance along a path transverse to the path of the light simultaneously with the movement of the optical aperture. The arrangement for moving the lenticular screen comprises means for guiding the screen along said predetermined path and a pivoted member, a connection between the pivoted member, at a position displaced from the pivot thereof, and the screen. Also a rack is connected to the pivoted member and a pinion engages the rack. A motor rotatably drives the pinion to thereby move the rack and thereby pivot the pivoted member and move the screen along the predetermined path a precise predetermined amount corresponding to the driving movement of the motor.
