Paper Abstract

A mid-infrared imaging camera head built around a 512 x 512 monolithic PtSi focal plane array is discussed. The pixel size of the focal plane array is 30 by 30 microns. The array uses a novel line-addressed charge-accumulation structure that allows a 54-percent fill factor using 2.5-micron minimum design rules. Effective frame rates exceeding 75 Hz are achieved using multiple readout registers (i.e., four each) when operated at 5 Mpixels/s. The array is cooled in a side-looking, liquid nitrogen dewar with a hold time greater than 8 hours. All the drive and signal processing circuitry necessary to operate the device and perform correlated-double sampling on the video signals are mounted in boxes attached to the dewar.
