Second Generation IR Sensor Design Analysis.
Abstract
The investigations and analyses performed during the course of this program lead to the following conclusions: A 3 - 5 micrometer, TE cooled IR system can be built using on focal plane CCD electronic processing technology, to yield high performance; Using CCD's, large arrays of detectors can be used which require few output leads from the dewar, thus decreasing mechanical complexity and heat loads; PbSe, because of its high impedance makes an ideal detector to interface with CCD's with several input scheme possibilities; A parallel scan system is used to conserve bandwidth and optimize scan efficiency; Individual row detector signals are delayed and added to reduce the requirements on the output shift register and background suppression; The requirements of the guidelines system can be achieved using a 540 element PbSe array; A family of systems, using modular techniques and high density array TE detectors can be built to meet a multiplicity of applications.
