Abstract

Various companies are now producing 2-dimensional CMT-Si hybrid focal plane arrays. These are complex devices and at present the accepted figures of merit describing the arrays vary significantly between devices of the same type. In infrared imager applications the spatial uniformity of the detector array, particularly with regards to parameters such as noise equivalent temperature difference (NETD) rather than the quality of individual pixels may determine the overall system performance. A small number of unresponsive elements can be effectively masked by correction algorithms in the imager electronics. Assessment apparatus capable of storing the output of all the photodiodes in a focal plane array up to 128 X 128 pixels in size has been used to determine the optimum operating point for three co-ordinate addressed devices, giving rise to a methodology for setting up this type of detector.
