Abstract: 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. One of the at least two detector arrays comprises a cooled mid-wavelength infra-red FPA. 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.

Abstract: A system simultaneously tracks multiple objects. All or a subset of the objects includes a wireless receiver and a transmitter for providing an output. The system includes one or more wireless transmitters that send commands to the wireless receivers of the multiple objects instructing different subsets of the multiple objects to output (via their respective transmitter) at different times. The system also includes object sensors that receive output from the transmitters of the multiple objects and a computer system in communication with the object sensors. The computer system calculates locations of the multiple objects based on the sensed output from the multiple objects.

Abstract: An infrared imaging device comprises an infrared imaging sensor to detect infrared light as heat, a temperature drift compensation amount calculator to calculate a temperature drift compensation amount in accordance with a temperature change of the substrate, with respect to a pixel output outputted from each of the plurality of pixels, a compensation amount calculation function generator to generate a function with the temperature of the substrate as an independent variable; and a timing controller to cause the infrared imaging sensor and the substrate temperature sensor to synchronously output data to the compensation amount calculation function generator for generating the function, wherein the compensation amount calculation function generator uses the data for generation output after the generation of the function as additional data for improving accuracy of the function.

Abstract: An apparatus detects a transient thermal gradient in a substrate. The apparatus is comprised of an electromagnetic radiation source configured to emit source electromagnetic radiation; a fast shutter configured to block the source electromagnetic radiation when closed, and open in response to a command to pulse the source electromagnetic radiation; a substrate support that supports a substrate disposed to emit a pulsed radiation from a back side of the substrate when the source electromagnetic radiation is pulsed through the substrate; and a detector configured to face the back side of the substrate. The detector is used to detect a transient thermal gradient in the pulsed radiation.
