Paper Abstract

We present details of a compact highly automated pulsed holographic camera system designed for the rapid production of image-planed white-light-viewable reflection holograms up to a size of 40 X 60 cm. The camera operates in two modes: Mastering and Copying. In the mastering mode a holographic plate (40 cm X 60 cm VRP-M Slavich) is placed in a special plate holder at the front of the main camera unit and two diffusers either side of this plate illuminate the object/subject to be holographed. The reference beam exits from the back of the main camera unit and is directed onto the plate by two small overhead mirrors. In copying mode, a processed holographic master is placed in a special rig and a new plate (VRP-M Slavich) having a size up to 40 cm X 60 cm is placed opposite and parallel to this master. In this mode two beams exit the main camera body at opposite sides and are directed by small tripod-mounted mirrors to illuminate the master and copy plates. The camera system is highly automated, providing instant switch-over from copying to mastering modes and permits digital electronic setting of all beam ratios. Machine options currently under development are discussed which include high-speed film copying and a digital mastering interface.
