    Abstract: Measuring the polarimetric response of an optical instrument includes the steps of: emitting light along an optical axis; receiving the light through first and second polarizers; and detecting the light received through the first and second polarizers, using a filter and a detector. A first set of measurements is obtained by measuring the intensity of light received through the first and second polarizers. A second set of measurements is obtained by placing an optical instrument along the optical axis in lieu of the filter and detector; and measuring the intensity of light received through the first polarizer, after the second polarizer has been removed. A third set of measurements is obtained using the optical instrument but having the second polarizer replace the first polarizer. The optical instrument may be characterized using the first, second and third sets of measurements. The characterization is completed without having to know the extinction ratios and the transmittance parameters of the polarizers.

    Abstract: A light emitting module testing apparatus includes a sensing unit and a controller. The sensing unit includes a photodiode array sensing light emitted from a light emitting module serving as a test object. The controller generates luminance information based on light sensed by the sensing unit, and sets an operating condition of the light emitting module serving as the test object by comparing the generated luminance information with a pre-set reference range. The light emitting module testing apparatus thereby senses luminance of light emitted from the light emitting module serving as a test object, and sets the operating condition of the light emitting module to have an appropriate luminance.

    Abstract: A calibration device for a radiometer includes an integrating cavity and a honeycomb blackbody mounted to the integrating cavity. A plurality of emitters are mounted to the exterior rim of the integrating cavity for transmitting narrow band wavelengths of light into and out of the integrating cavity. A controller, selectively, activates one or more emitters to radiate a single narrow band wavelength of light during an ON period and turn OFF during another period. A plurality of reference detectors are also mounted to the exterior rim of the integrating cavity for measuring the intensity of each narrow band radiation outputted from the integrating cavity. The reference detectors are effective in determining changes in intensity output by each of the narrow band emitters from the integrating cavity. The measured changes in intensity outputted by the emitters are used to calibrate the radiometer with the changes traced back to a NIST standard.

    Abstract: The present invention comprises an approach for calibrating the sensitivity to polarization, optics degradation, spectral and stray light response functions of instruments on orbit. The concept is based on using an accurate ground-based laser system, Ground-to-Space Laser Calibration (GSLC), transmitting laser light to instrument on orbit during nighttime substantially clear-sky conditions. To minimize atmospheric contribution to the calibration uncertainty the calibration cycles should be performed in short time intervals, and all required measurements are designed to be relative. The calibration cycles involve ground operations with laser beam polarization and wavelength changes.
