Abstract

Evaluation of infrared sensor performance begins with integration on an optical test station and initial acquisition of a source target image. Preliminary performance evaluation includes sensor radiant response, image performance, and sensor alignment. Integration and preliminary performance evaluation may be expedited by the use of an innovative target consisting of a cold background surrounding a hot extended source with a thin, cold wire obscuration. This paper describes an appropriate target geometry and provides a nomogram that allows estimation of sensor focal error based on an observed ratio of target image response between two detector elements.
