Paper Abstract

A proposal for adapting principles of stereoscopy with the technology of optics and electronics for airborne reconnaissance, is a basic system design to equip drone aircraft with instrumentation consisting of two television cameras, related ancillary equipment, and radio link for transmitting television signals to other airborne stations and ground station television monitors. Television cameras are alternately rotated 90° side-to-track of vehicle motion, package-mounted and gyroscopically stabilized. Empirical to system design, a delay-point-of-focus of the cameras can be fixed or variable. For variable control, a radio controllable computer function for sine-cosine, fore-aft camera pivot, to vary the delay-point-of-focus and angular convergence, is possible. The two television cameras can also be gimbal mounted to permit radio controllable and simultaneous lateral traversing left and right to direction of track. A memory type subsystem at each station, integral to one of the two television monitors, complements the delay-point-of-focus function, for simultaneous stereo-picture display. Refractive or reflective type stereoglasses, or polarize type stereoglasses with matching polarize cover glass plates for each television monitor, depending upon system requirements, provides additional optical adaptation for stereo viewing by photo interpreters.
