Uncooled Long-Wave Infrared Small Pixel Focal Plane Array and System Challenges

Abstract

There is a strong motivation for smaller pixels based on end-user demand for lower-cost, higher-resolution camera systems both for military and commercial applications. Uncooled detector technology fits the need for a low size, weight, and power system. We explore the tradeoffs and challenges to achieving pixel designs smaller than the current 17-microns state-of-the-art detectors without loss in sensitivity or resolution. For illustration we consider a 12-microns design. We also address modulation transfer function issues as the pixel size shrinks, and examine the difference between the performance of present devices and the theoretical performance limit for uncooled detectors.
