Abstract: An optical module includes: a measuring device including a measuring portion that measures light reflected at a measurement position of a measurement target, a light source that radiates light onto the measurement position in a direction crossing a measurement optical axis oriented from the measurement position to the measuring portion, and a window through which light incident on the measuring portion passes; and a shutter that opens and closes the window of the measuring device. The shutter is provided with a reference object disposed closer to the measuring portion side than the measurement position on the measurement optical axis, on a face of the shutter facing the measuring portion when closing the window, and the optical module includes a light guide that guides the light from the light source to the reference object when the window is closed by the shutter.

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.

Abstract: Described are a shutter assembly, a spectrometer, and a method for calibrating a spectrometer. For example, the method may include positioning a shutter including a mirror into a first position in an illumination path of an excitation light beam such that a measurement window is blocked. The mirror may be operable to direct at least one of: (1) the illumination path to a spectral calibration material, (2) a first collection path extending from the spectral calibration material, and (3) a second collection path of a spectral calibration light beam. The method may include directing a returned light from the receiving optics unit to an imaging device; processing the returned light at the imaging device into one or more image signals; analyzing and comparing the image signals with approved image signals; and providing an indication of whether the comparative results of the analysis are within acceptable tolerances.
