High-speed, High-Resolution Focal Plane Array Imaging System

摘要

We have developed a high-resolution, high-speed InSb Focal Plane Array Imager which was built and delivered by Indigo Systems, Inc., of Santa Barbara, CA for use in research and development of thermal wave imaging and nondestructive inspection (NDE) aircraft structures. The design team included Indigo Engineers and faculty from Wayne State. The imager was designed with features intended specifically for use in hangar and field conditions. It includes a sunlight readable monitor, and a 50 foot cable for remote operation. Furthermore, facilities are provided at the camera end of the cable for control of the image acquisition of the computer, so that it can be used as a single-operator system. The camera itself has a very fast, large-area focal plane array (640 x 512 pixels), a 14-bit dynamic range digitizer, and is capable of acquiring image data a rate of 40 Mpixels/s. The dynamic range can be extended even further by use of a novel switchable array integration time.
