Abstract

In 1993, FLIR SYStems, Inc. developed and established production of an MWIR staring sensor based upon affordable and reliable platinum silicide staring focal plane array technology. This sensor incorporates many new features in addition to the FPA technology that makes it well suited for a wide variety of applications. The FPA is a 240 X 320 area array of Schottky detectors read out in a snap shot progressive scan mode. The FPA architecture is a hybrid bump bonded detector to a CCD readout for high sensitivity and uniformity. The sensor uses a new miniature linear cooler with an integral dewar; this approach provides unsurpassed reliability and low power at affordable cost. The sensor electronics contain electronically programmable logic to read out the FPA and format the detector gain and offset nonuniformity correction circuitry. The video output can be controlled by manual gain/level or by automatic mode. The optics are designed to be low cost, light weight and easily interchangeable to serve a wide variety of applications. The sensor is designed to support all video formats and be user friendly. The compact size and low power is well suited for portable applications.
