The research of non-uniformity correction technologies for resistor array dynamic infrared scene projector

Abstract

The resistor array devices are commonly used to produce dynamic two dimensional infrared images in the infrared scene projectors. A non-uniformity caused by many factors is the main source of image fixed pattern noise of the projectors based on resistor array devices. A prior non-uniformity correction procedure must be done before the dynamic infrared image generation for the hardware-in-the-loop simulation test and evaluation. In this paper, the developments and details of the non-uniformity correction technologies for resistor array dynamic infrared scene projector are investigated. The research is commenced directed towards understanding the cause of spatially-distributed radiance non-uniformities of resistor array device, and the fundamental elements that underlie the non-uniformity correction technologies in dynamic infrared scene projection system.
