CRYOGENIC RADIATION MONITORING MICROSCOPE

THE PROPOSED DEVICE IS AN INFRARED CRYOGENIC MICROSCOPE FOR MEASURING THE RADIOMETRIC OUTPUT OF SELECTIVELY HEATED PIXELS OF IR SCENE GENERATORS. THE MICROSCOPE COVERS THE WAVELENGTH REGION FROM 1 TO 125 MICRONS CAN RESOLVE 0.0001" INCREMENTS ON THE MOSAIC SURFACE. THE MICROSCOPE HAS SUFFICIENT DYNAMIC RANGE TO MEASURE TEMPERATURES FROM APPROXIMATELY 40K TO 1500K. INTERCHANGEABLE OBJECTIVE ELEMENTS ALLOW VARIABLE MAGNIFICATION FROM 1 X TO 40 X IN DISCRETE STEPS. REMOTELY CONTROLLED FILTERS PROVIDE ROUGH SPECTRAL MEASUREMENTS WHILE A REMOTELY CONTROLLED PINHOLE APERTURE PROVIDES VARIABLE SPATIAL RESOLUTION. THE DEVICE CAN EVALUATE EITHER PULSED OR CONTINUOUSLY HEATED PIXELS AND CAN ACCURATELY SCAN A LARGE AREA MOSIAC (TO 8" X 8").
