ULTRA-VIOLET DYNAMIC SCENE GENERATOR

WE PROPOSE THE DEVELOPMENT OF A PROGRAMMABLE ULTRA-VIOLET (UV) DYNAMIC SCENE GENERATOR (UVDSG) TAILORED TO PERFORM HARDWARE-INTHE-LOOP (HIL) SIMULATION OF UV SENSORS USED IN MILITARY SYSTEMS. WE WILL INVESTIGATE A SPECIAL PROCESS FOR FABRICATING A 2-DIMENSIONAL ARRAY OF MICROSCOPIC, DEFORMABLE MIRRORS ON A SILICON WAFER, DESIGN AN ON-CHIP CIRCUIT FOR CONTROLLING THE MIRROR DEFORMATION AND DESIGN A CONTROL PROCESSOR FOR OPERATING THE ARRAY. EACH MIRROR WILL BE INDEPENDENTLY DEFORMED TO ANY DESIRED ANGLE WITHIN ITS DEFORMATION RANGE BY A PROGRAMMABLE ELECTRICAL VOLTAGE. THUS, THE MIRRORS WILL BE MADE TO REFLECT AN UV BEAM IN A CONTROLLED MANNER. WHEN THE MIRRORS OF THE ARRAY ARE MADE TO REFLECT INDEPENDENTLY, A 2-DIMENSIONAL UV SCENE WILL BE PROJECTED WHEN A COLLIMATED UV BEAM IS INCIDENT ON THE ARRAY. THIS SCENE WILL THEN BE PROJECTED ONTO THE SENSOR UNDER TEST OR SUBJECTED TO HIL SIMULATION. DUE TO ITS HIGH FRAME RATE, THE ARRAY WILL BE IDEAL FOR PROJECTING FAST-CHANGING SCENES ONTO THE SENSOR SYSTEM TO SIMULATE THE UV DYNAMICS EXPERIENCED BY THE SENSOR.
