A fully operable laboratory model of the Remote Viewing System was designed and built. The system consists of a TV camera and TV projector both equipped with a non-linear lens, i.e. a lens that matches the human eye acuity function with excellent resolution capability near the optical axis, but greatly reduced resolution capability in the peripheral areas. The camera and projector are slaved together by a digital servo system. An operator can steer the camera and thus the projector by use of a helmet mounted tracker. As the operator rotates his head to observe off axis display detail, the camera is commanded to rotate and the projector follows. Thus, high acuity detail is retained on the foveal axis of the observers eyes. This system allows wide field-of-view 160 deg remote viewing of scenes, with resolution comparable to human vision, using conventional TV system bandwidths. Detailed performance analyses of the current design indicate better acuity is possible by fabricating new rear spline elements for the non-linear lenses and redesigning the projector optical relay. Through these efforts, 1 milliradian performance should be readily obtained. Performance better than this appears to be limited by a diffraction problem inherent in the projector Schlierin optics and would require use of a different type of projector.
