Abstract: An approach for controlling ultraviolet intensity over a surface of a light sensitive object is described. Aspects involve using ultraviolet radiation with a wavelength range that includes ultraviolet-A and ultraviolet-B radiation to irradiate the surface. Light sensors measure light intensity at the surface, wherein each sensor measures light intensity in a wavelength range that corresponds to a wavelength range emitted from at least one of the sources. A controller controls the light intensity over the surface by adjusting the power of the sources as a function of the light intensity measurements. The controller uses the light intensity measurements to determine whether each source is illuminating the surface with an intensity that is within an acceptable variation with a predetermined intensity value targeted for the surface. The controller adjusts the power of the sources as a function of the variation to ensure an optimal distribution of light intensity over the surface.

Abstract: The present invitation relates to an optical radiation measurement method based on light filter units, comprising the steps of: 1) providing characteristic filter units and correction light filter units in front of detection units to obtain multiple measured response values of an object to be detected; and, 2) selecting one or more sampling regions within a waveband to be detected, and calculating, according to a corresponding simultaneous expression/equation system of the measured response values, a spectral power distribution within the waveband to be detected. In this method, by introducing a small number of correction light filter units, the spectral power distribution within the entire waveband to be detected can be obtained without using a large number of narrow waveband color filters. In addition, a light radiation measurement apparatus is disclosed.

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.
