1. An infrared scene display comprising:
- a two dimensional array of miniature infrared radiating elements;
coupling means coupling the radiation of said two dimensional array of miniature infrared radiating elements to a display plane, said coupling means comprised of a coupling device for each infrared radiation element; and
spacing means for spacing each infrared radiating element from each coupling device, each of said infrared radiating elements being spaced from said coupling means a preselected distance that is optically equivalent to being in contact while remaining thermally isolated;
whereby said infrared scene display can be used to test infrared detecting sensors and focal planes.

Abstract
An infrared scene display for testing infrared detectors and arrays comprising a two dimensional array of contiguous areas each of which contains an infrared radiating element. A plurality of microlens formed on a substrate are coupled to the array of infrared radiating elements. Each infrared radiating element is sufficiently spread from its associated microlens to provide good thermal insulation but is close enough to operate in an immersion mode. In this configuration, the infrared radiating elements behave optically as though they are in contact with the microlens substrate though they remain thermally isolated.
