Abstract
A three-dimensional data acquisition and display system using fiber optics is described. The system consists of a range-gated pulsed laser illumination source and a direct view image intensifier or remote view camera tube sensor. Such sensors have been effective in locating, ranging, and observing targets which may be located behind a scattering medium such as clutter, haze, or camouflage. The ability to control the viewing time of the sensor allows the back-scattered light to be gated out, thereby providing enhanced detection and recognition capability. The three-dimensional information is obtained by range-gating the different z-planes in time. The display system consists of fiber optics slugs of varying thicknesses, and each frame in the object plane is projected on a different fiber optics slug. This entire data acquisition and display occurs at a speed faster than the flicker frequency of the eye, thus penetrating a real-time, three-dimensional view of the object. A prototype of the three-dimensional display system is explained and various alternate approaches for data acquisition, data recording, and data display is described.
