Abstract: A micro-electro-mechanical (MEMS) based surveillance system and a method for using the MEMS based surveillance system are described herein for imaging an object. In one example, the MEMS based surveillance system can record images of an object from four different wavelength regions including visible light, near-infrared light, infrared light, and far infrared light.

Abstract: A multi field of view hyperspectral imaging device and method for using the same which can be used in many applications including short wavelength infrared (SWIR) and long-wavelength infrared (LWIR) applications are presented herein. In one embodiment, the multi field of view hyperspectral imaging device comprises multiple fore optics, multiple fold mirrors, a slit including a multiple openings, a spectrometer, and a 2-dimensional detector.

Abstract: A hyperspectral imaging system and a method are described herein for using an array of optical homogenizing elements to reduce spectral noise in an image of a real-world scene. In one embodiment, the hyperspectral imaging system and method use the array of optical homogenizing elements for homogenizing a spatial, an angular, and a polarization distribution of light from different elements within the real-world scene before it is measured by a spectrometer.

Abstract: Disclosed is a radiation detector which includes a photoconductive detector and a modulator which modulates radiation passing to the photoconductive detector from a radiation source. An AC bias source is connected to the photoconductive detector and provides at least two levels of bias thereto. The modulator supplies synchronization signals to the AC bias source such that the level of bias supplied to the photoconductive detector is synchronized to the modulation of the radiation by the modulator. An integrator is connected to and receives an output signal generated by the photoconductive detector.

Abstract: A method for accurately converting to an electrical signal a modulated optical signal, the modulation frequency of which randomly varies in a narrow range about a predefined optimum modulation frequency, includes the steps of receiving the optical signal at an optical detector, producing as an output of the optical detector an electrical signal corresponding to the optical signal, the amplitude of which electrical signal varies with frequency, and modifying the amplitude of the electrical signal, depending on the frequency of the electrical signal, inversely to the variation of the amplitude of the electrical signal with frequency caused by the optical detector.

Abstract: A method and apparatus for non-invasive determination of the concentration of at least one analyte in a mammal. A portion of the body of the mammal is irradiated with incident radiation, where the incident radiation includes two or more distinct bands of continuous-wavelength incident radiation. The resulting radiation emitted from the portion of the body is sensed and a value for the concentration of the analyte is derived therefrom.
