Abstract: We have developed a new Acousto-Optic Tunable Filter (AOTF) for implementation as a spectrally selective element for hyperspectral imaging applications in the NIR (.8 - 1.7 micron) and MWIR (2.5 - 4.5 micron) ranges of the optical spectrum. The new AOTF has high spectral resolution (about 3/cm) and requires relatively low RF drive power. It has a broad acceptance angle and increased diffraction efficiency for enhanced optical throughput. In combination with a 2-D IR focal plane array the new AOTF allows for real time hyperspectral imaging of both self-emitting sources, such as astronomical objects or rocket exhaust plumes, and externally illuminated absorbing/reflecting specimens.
