Abstract: A divided-aperture infrared spectral imaging (DAISI) system that is structured to provide identification of target chemical content in a single imaging shot based on spectrally-multiplexed operation. The system is devoid of spectral scanning acquisition of infrared (IR) spectral signatures of target content with an IR detector and does not require content.

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 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.

Abstract: A method and spectral light-based apparatus with an embedded (built-in) spectral calibration module for acquiring multi-spectral reflectance images from a digital camera are disclosed. The apparatus may be an attachment device, which may be integrated with a consumer digital camera (such as smartphone camera), and may measure and/or estimate spectral reflectance and true color values for an object recorded by the camera. An example apparatus comprises an array of monochromatic light sources, preferably pulsed LEDs, irradiating in a time-multiplexed manner to generate light spectra in the range of 400 nm-1000 nm, an optical lens to limit the field of view of the attached camera, an electro-mechanical shutter or plate with its inner (reflection) surface coated with a diffuse reflectance standard to ensure flat spectral response, and an interface module for synchronizing the time-multiplexed light spectra with the coated shutter opening and closing and with the digital frames acquired by the camera, such that the true spectral reflectance and true color value of an object can be measured.
