Development of laser-based direct-write projection methods: sensor optics and system characterization issues

This paper describes the investigation and potential utility of using the Direct Write Scene Generator (DWSG) to project onto a sensor system's focal plane array (FPA) through its optical telescope. The test approach requires development of magnifier/collimator systems to expand the DWSG output to the sensor telescope. A lens system has been procured to facilitate the projection to the full array of a standard CCD with an attached lens system. A demonstration of operation of the DWSG through camera optics has been recorded. The capability of the DWSG system to measure FPA crosstalk has been examined in some detail.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
