Infrared (IR) staring arrays offer significant performance improvements over mechanically scanned systems, if the signals from these focal planes can be conditioned for use by imaging displays or signal processors. IR staring arrays offer the potential for increased sensitivity, wide dynamic range, and short frame time, if the problems associated with the readout of data from these arrays can be solved in an efficient manner. Some of the func-tions included in this signal conditioning are: nonuniformity compensation, local area gain and brightness control, detector integration time control, and multiple frame composition. Nonuniformity compensation and local area gain and brightness control were covered in earlier papers. 1,2,3 This paper deals with integration time control and the resulting multiple frame composition possible with focal plane arrays.
