DMD IR BACKGROUND SCENE GENERATOR

EFFECTIVE GROUND TESTING OF LONG-WAVELENGTH INFRARED (LWIR) PROXIMITY FUSES REQUIRES A SYSTEM CAPABLE OF GENERATING REALISTIC IA SCENES IN THE 8-12 MICRON REGION OF THE ELECTROMAGNETIC SPECTRUM. IN ORDER TO ACCURATELY DEVELOP AND EVALUATE DEVICES UNDER TEST THE SCENE GEN$RATION SYSTEM MUST SIMULATE AS CLOSE AS POSSIBLE THE ACTUAL IR IMAGE SEEN BY THE PROXIMITY FUSE IN THE FIELD. THE NAVAL WEAPONS CENTER (NWC) IS DEVELOPING A SCENE GENERATION SYSTEM THAT USES 1/10 TO 1/4 SCALE MODELS OF TARGETS OF INTEREST FOR LWIR PROXIMITY FUZE TESTING. WHILE THIS SYSTEM CAN SIMULATE THE IR EMISSION OF TARGETS OF INTEREST, IT DOES NOT HAVE THE CAPABILITY OF SIMULATING THE BACKGROUND IR SCENE SURROUNDING THE TARGET. THIS PROPOSAL ADDRESSES THE DEVELOPMENT OF AN IR BACKGROUND SCENE PROJECTOR THAT WILL PRODUCE TIME-VARYINGBACKGROUND SCENES DERIVED FROM LWIR VIDEO IMAGERY FOR THE NWC IR SCENE GENERATOR.
