    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 transient grating (TG) is used as an optical gating element with sub-picosecond time resolution for luminescence measurements from a photo-detector array. The transient grating is formed in a gate medium by one or more pulsed gate beams. For photoluminescence measurements such as photoluminescence spectroscopy or imaging, a source is excited by a pulsed excitation beam, and the pulsed gate beams are synchronized to the pulsed excitation beam with an adjustable delay between the excitation of the source and the formation of the TG. Moreover, a source or its spectra can be imaged at two different regions of the photo-detector array at two different times spaced in time by a selected duration of time with sub-picosecond resolution over a range of a nanosecond or more. A beam from the source is deflected to the different regions by changing the frequency or geometry of the pulsed gate beams.
