Abstract

Low NETD's, coupled with other improvements in camera design and manufacturing, helps to further enable a new class of very demanding imaging applications in medicine and medical research.. The evolution of QWIP FPA over the past five years, with their low NETD, detector uniformity, and high pixel yield, along with improvements in camera control and processing electronics, represents key technical innovations responsible for the reemergence of medical infrared imaging through the development of a new infrared medical imaging technique called Dynamic Infrared Imaging or DIRI. The QWIP's high thermal and spatial resolution coupled with very fast data acquisition capabilities fill the essential requirements of DIRI. Other features required by DIRI applications are the need for stable operation with drifts in the image below a few mK, which allow longer data collecting time. Longer data collection time provides the camera the capability to detect the functional behavior of the autonomic nervous system which operates on a time scale of 0.1 to 0.2Hz.
