Real time, large volume, moving scene holographic camera system
Abstract
A holographic motion picture camera system is described which produces resolution of front surface detail. The system utilizes a beam of coherent light and means for dividing the beam into a reference beam for direct transmission to a conventional film transport, and three reflection signal beams for transmission to the film transport by reflection from the three orthogonal sides of a moving scene. The system is arranged so that critical parts of the system are positioned on the foci of three interrelated mathematically-derived ellipses. The camera has the theoretical capability of producing motionpicture holograms of an object moving at speeds as high as 900,000 cm/sec (about 21,450 mph). The system has the capability of handling objects of relatively large volume moving in a random direction anywhere within a volume.
