Abstract
This paper describes recent developments in the area of target projection technologies for measurement of staring IR sensor image quality. In addition to the latest reflective target techniques, we describe a novel Variable Slit Target (VSTa) device, which allows extremely precise slit, edge, and rectangular features to be generated at the focus of a reflective target projection system, and stepped across a UUT’s FOV with a high degree of sub-pixel resolution. We also present the Collimator Line of Sight Alignment Techniques (CLOSAT) as a means of both precisely aligning the target projector and adding dynamic capability to static targets. The discussion includes a review of the applicability of VSTa and CLOSAT to current and emerging UUTs incorporating advanced staring focal plane technologies.
