摘要： A particle discriminator using circularly polarized light projected through a channel having target particles. Light may be propagated through the channel, with some light scattered separated into forward angle scattered light, small angle scattered light and unscattered light. The forward angle scattered light may be linearly polarized and detected. The small angle scattered light may be linearly polarized in a direction orthogonal to the direction of the polarization of the forward angle scattered light, and at least both these kinds of light may be detected. Data from these detected kinds of light may be analyzed to discriminate particles from one another.

摘要： A Laser Imaging, Detection and Ranging (LIDAR) system that automatically adjusts laser output so that no eye damage occurs to human targets. In one example, a component automatically measures range to targets in a field of view and determines the closest targets based on the measured range. A laser device outputs a laser beam and a controller adjusts one of pulse repetition frequency, power, or pulse duration of the laser device based on the measured range of the closest target in order to comply with a predefined eye safety model.

摘要： Disclosed is a tunable multispectral optical apparatus for forming a spectrally processed image of a scene having finite angular extent or alternatively a point source of light, both of which may include multispectral components. A spatial filter is selectively positioned between a hybrid fore-optic and a hybrid reimaging optic, both of which include a diffractive optic. Spectral selectivity is obtained by proper positioning of the spatial filter relative to the intermediate image formed by the hybrid fore-optic before impinging on the hybrid reimaging optic. The tunable multispectral optical apparatus of the present invention may take the form of a bandpass filter or a bandstop filter depending only on the choice of spatial filter--blocking or passing selective wavelength components of the intermediate image.

摘要： A monolithically constructed infrared, tunable Fabry-Perot cavity filter-detector for spectroscopic detection of particular substances having an absorption line in the wavelength range from 2 to 12 microns. The filter-detector has a hermetically sealed Fabry-Perot cavity that has a mirror which has an adjustable distance relative to another mirror of the cavity. The former mirror is adjusted by piezoelectric film on the mirror support or with piezoelectric stacks or wall supporting the mirror. There may be electrodes situated near the mirrors for capacitive sensing of the distance between the mirrors. Light to be filtered and detected comes in through a window wafer which may have diffractive or refractive microlenses, plus an optional spatial filter. After passing through the window wafer, the light is filtered by the tunable mirrors of the Fabry-Perot cavity. The portion of the light that is passed by the cavity is detected by an infrared microbolometer or a CCD array. The cavity and detector are hermetically sealed in a vacuum.
