    Abstract: A flashlamp control system is provided with a capacitor that is statically electrically connected to the high voltage power supply, and a current sensing component is then electrically connected to the static capacitor and digital control electronics to monitor the charge current and/or the discharge current to static capacitor. A dynamically switchable capacitor electrically may also be connected to the high voltage power supply and digital control electronics for isolating the dynamically switchable capacitor from the high voltage power supply based on the monitored charge current and/or discharge current. One or more homogenizing element, comprise of an air gap, diffusing homogenizing element, imaging element, non-imaging element or light pipe homogenizing element, may be disposed in the light path proximate to the flashlamp, such as a multichannel distributor if present, to decrease the coefficient of variation of the optical signal, either temporally and spectrally, or both.

    Abstract: The present invention is an apparatus for forming a spectrally weighted value from received multispectral radiation. The spectral weighting is done optically prior to detection of the received radiation by dispersing the received multispectral radiation into a plurality of wavelength bin areas. This dispersed radiation is then passed through a weighting filter which includes first and second filter elements for each of the wavelength bin areas. The filtered radiation is then converged to corresponding detectors with the spectrally weighted value formed by the difference between the signals of the first and second detectors. A pair of filters, two detectors and a subtracter are employed to produce a generalized weight factor having positive or negative weights. This system can form one or more spectrally weighted values from the radiation from a single pixel, or one spectrally weighted value form the radiation from a plurality of pixels. The addition of a polarization filter permits the formation of spectrally weighted values for various polarizations of a single pixel.

    Abstract: A method and apparatus for controlling the spectral components of a light beam are described. The apparatus comprises means (3-7) for generating a collimated light beam; means (9) for dispersing the collimated beam; a mask (1) including an aperture (2) the size of which is such that a portion of the dispersed beam passes through the aperture in use; and movement means (not shown) for causing relative transverse movement between the light beam and the aperture. A memory (not shown) is provided for storing in use a profile of the relative transverse movement between the light beam and the aperture (2) required to obtain a desired spectral response in the transmitted light beam, the movement means being responsive to the stored profile to cause relative transverse movement in accordance with the predetermined profile.
