D-1183 6-15-78 TELEVISION COMPATIBLE THERMAL IMAGING SYSTEM ABSTRACT OF THE DISCLOSURE A thermal imaging system generating high resolu- tion images at commercial T.V. rates while scanning rela- tively large apertures comprising a facet mirror mounted for rotation about a rotational axis, a framing mirror mounted on axis for oscillation about an oscillatory axis, and an off axis, magnifying relay lens system for reimag- ing the pupil at the facet mirror onto the framing mirror so that there is a real pupil at the framing mirror with no image artifacts. The relay lens system is located in the optical path between the facet mirror and the framing mirror. The relay lens system defines an image plane and at least one point blackbody is located substantially at the image plane for purposes of providing a video refer- ence and calibration. A detector receives the focused beam of radiation reflected by the facet mirror for sub- sequent display on commercial T.V. monitors. The detector shares vacuum with the high-speed scanner.
