17 June 1996 Agile band-pass tunable filter in gas measurement

The agile bandpass tunable filter (ABTF) is a new instrument with variable resolution and center wavelength that allows MWIR and LWIR infrared cameras to recognize spectral images that are characteristic of specific materials, including gases. Benefits of this new technology include the ability to: (1) Task infrared camera-based sensors to search for specific materials, and (2) Transform infrared camera data into signatures easily understood by untrained users. The application of a working prototype hyperspectral ABTF is described. The prototype is capable of rapidly selecting bandpasses from among several spectral resolutions, and is easily tunable over the MWIR spectral band. The application of the ABTF to signature imaging of gases is shown.
