Abstract
The viability of extending the Direct Write Scene Generator (DWSG) to project to a sensor system with an optical telescope installed has been investigated. The test approach requires development of transmissive or reflective screens and/or collimator systems to expand the DWSG output to the sensor telescope. Several optical configurations have been examined to accommodate this capability. Measurements of the optical spot size on a camera with a zoom lens have been compared to CODE V predictions. Analysis has been performed to determine the practical limitations of this configuration with regard to testing sensors with a set field of view. A demonstration of operation of the DWSG through camera optics has been accomplished. The utility of this new capability to closed-loop operation has also been examined.
