Abstract
THE OBJECTIVE OF THIS RESEARCH PROGRAM IS TO DEVELOP A PORTABLE, RAPID-SCANNING WIDEBAND IMAGING SPECTRORADIOMETER (SWIS) TO ADDRESS THE NEED FOR A REAL-TIME INSTRUMENT THAT CAN SIMULTANEOUSLY OBTAIN BOTH IMAGING AND SPECTRAL DATA IN THE 1 TO 12 UM WAVELENGTH RANGE. OPTRON'S TECHNIQUE USES PASSIVE DISPERSIVE OPTICAL ELEMENTS (GRATING AND LENSES) TO SPECTRALLY SEPARATE THE INCIDENT RADIATION, WHILE PRESERVING IMAGE RESOLUTION. THIS SPECTRAL IMAGE CONTINUUM IS FOCUSSED SIMULTANEOUSLY ONTO LINEAR SPATIAL LIGHT MODULATORS, WHICH SELECT THE SPECIFIC NARROW-BAND SPECTRAL REGION TO BE EXAMINED. THE FILTERED WAVELENGTHS OF INTEREST ARE THEN DISPERSION COMPENSATED AND REIMAGED ONTO THE APPROPRIATE IMAGING DETECTORS (E.G., CCD CAMERAS) BEFORE BEING DOWNLOADED TO AN ELECTRONIC COMPUTER FOR POST PROCESSING.IN ITS ULTIMATE FORM, THE DEVICE CAN COVER THE WAVELENGTH RANGE BETWEEN 1 UM AND 12 UM, PROVIDE WAVELENGTH SWITCHING IN < OR - UM, AND BE CAPABLE OF LINEAR OR RANDOM SPECTRAL SCANNING. THIS TECHNIQUE HAS THE ADVANTAGES OF HIGH-SPEED SWITCHING, BROAD-WAVELENGTH BAND COVERAGE, LOW-POWER CONSUMPTION, MEDIUM-VOLTAGE CONTROL (< OR - 500V), AND RELATIVELY REASONABNLE MANUFACTURING COST DUE THE USE OF STANDARD PASSIVE AND ELECTRO-OPTIC MATERIALS. THE DEVICE SCANS ELECTRO-OPTICALLY AND HAS NO MOVING PARTS.
