Abstract: An imaging transform spectrometer, and method of operation thereof, that is dynamically configurable “on demand” between an interferometric spectrometer function and a broadband spatial imaging function to allow a single instrument to capture both broadband spatial imagery and spectral data of a scene. In one example, the imaging transform spectrometer is configured such that the modulation used for interferometric imaging may be dynamically turned ON and OFF to select a desired mode of operation for the instrument.

Abstract: An optical spectroscopy method and apparatus increases signal to noise ratio of detected signals. Sample light passed through a sample includes attenuated light pulses and characteristic light located between the attenuated light pulses, the characteristic light formed by interaction between light pulses incident the sample and sample molecules. The attenuated light pulses are substantially removed from the sample light emerging from the sample prior to detection, to increase signal to noise ratio of the detected signal.

Abstract: A frame for optics used in interferometers that may include different materials having substantially similar, identical, or as close as practicable coefficients of thermal expansion from the material(s) used to make the beamsplitter and/or compensator without warping, bending, tilting or distorting the optics. The beamsplitter and/or compensator are mounted onto the frame of the interferometer using a three-point method of mounting, preferably using three pins for each component. Preferably, the pins are made of the same material as the beamsplitter and compensator, and all three components are made of Potassium Bromide (“KBr”) or Calcium Fluoride (“CaF2”) such that the optic instrument can operate to scan into the mid or far infrared. Stability in optical alignment is therefore achieved without requiring the optic instrument include only one material. The invention provides stability in situations where it is not possible to utilize a single material for every component of the interferometer.
