An IR scene projector having an array of resistive elements which radiate a predetermined pattern of IR energy. A collimator in front of the array has a plurality of hollow chambers, each positioned in front of a resistive element. Each chamber has a reflective inner surface which directs any radiation from the resistive elements which impinges upon the surface to a more forwardly direction, thus increasing the intensity of the projected pattern.
