摘要： The present disclosure relates to an apparatus for simulating a black body spectrum. The apparatus makes use of a broadband light source and a light guide configured to receive light generated by the light source and to generate first and second optical signals. A first signal processing subsystem may be used to enable adjustment of both a signal spectrum and an intensity of the first optical signal. A second signal processing subsystem may be used to enable adjustment of both a signal spectrum and an intensity of the second optical signal. A beam cube may be used to combine the first and second optical signals to produce a final light output signal having a desired signal spectrum and a desired intensity.

摘要： A polarization and color sensitive pixel device and a focal plane array made therefrom. Each incorporates a thick color/polarization filter stack and microlens array for visible (0.4-0.75 micron), near infrared (0.75-3 micron), mid infrared (3-8 micron) and long wave infrared (8-15 micron) imaging. A thick pixel filter has a thickness of between about one to 10× the operational wavelength, while a thick focal plane array filter is on the order of or larger than the size or up to 10× the pitch of the pixels in the focal plane array. The optical filters can be precisely fabricated on a wafer. A filter array can be mounted directly on top of an image sensor to create a polarization camera. Alternatively, the optical filters can be fabricated directly on the image sensor.

摘要： A radiation thermometer has a broadband light source which generates broadband light; an optical filter which, when the broadband light is incident on the measuring target object, passes only light in a predetermined wavelength range of reflected light and heat radiation light from a measuring target object; a light receiver which receives the light in the predetermined wavelength range through the optical filter; and a calculator which calculates a temperature of the measuring target object by using reflected light intensity and heat radiation intensity of the light in the predetermined wavelength range received by the light receiver, wherein an emission spectrum of the broadband light is a spectrum with a full width at half maximum which is equal to or wider than the predetermined wavelength range, and with light intensity increasing while a wavelength thereof becomes longer in the predetermined wavelength range.

摘要： Various embodiments disclosed herein describe a divided-aperture infrared spectral imaging (DAISI) system that is adapted to acquire multiple IR images of a scene with a single-shot (also referred to as a snapshot). The plurality of acquired images having different wavelength compositions that are obtained generally simultaneously. The system includes at least two optical channels that are spatially and spectrally different from one another. Each of the at least two optical channels are configured to transfer IR radiation incident on the optical system towards an optical FPA unit comprising at least two detector arrays disposed in the focal plane of two corresponding focusing lenses. The system further comprises at least one temperature reference source or surface that is used to dynamically calibrate the two detector arrays and compensate for a temperature difference between the two detector arrays.

摘要： A flame detector incorporates visible and near infrared sensors in common with processing circuits to form processed instantaneous, dc type, signal values minus an average value and peak-to-peak ranges of values of ac-type signals over a measurement time interval on the order of three seconds. The resulting values are further processed to determine the presence of a fire condition by comparing them to a predetermined threshold.

摘要： An infrared camera system is provided to detect absorption of infrared radiation in a selected spectral bandwidth. In one example, an infrared camera system includes a lens adapted to receive infrared radiation from a survey scene comprising one or more gasses. The infrared camera system also includes a focal plane array comprising a plurality of quantum well infrared photo detectors (QWIPs). The QWIPs are tuned to detect a limited spectral bandwidth of the infrared radiation corresponding to at least a portion of an infrared absorption band of the one or more gasses. The infrared camera system also includes an optical band pass filter positioned substantially between the lens and the focal plane array. The optical band pass filter is adapted to filter the infrared radiation to a wavelength range substantially corresponding to the limited spectral bandwidth of the QWIPs before the infrared radiation is received by the focal plane array.
