Paper Abstract

An Infrared Dynamic Scene Generator (IRDSG) was developed at Ball Aerospace Systems Division (BASD) in order to test an integrated sensor/processor. Using halftone images silkscreened on the surface of a mirror, the DSG presents to the sensor a replica of the inband radiances of a selected scene, taken from a digital database. The mirror with the scene printed on it is mechanically moved across the sensor's field of view. The energy from a constellation of simulated point targets is added to the image by a tuned beam-splitter. Their position and motion are independently controlled. Target multiplication increases the number of simultaneous tests per run while allowing the location of extremely faint targets to be known a priori. The line of sight of the sensor is also controlled for the simulation of scanning routines and platform jitter. The system is simple to set up and operate, has a wide dynamic range and is inherently flicker free. We discuss the implementation of each of the subsystems including two processes for transferring the image from the digital database to the reflectance mapped mirror.
