Paper Abstract

This paper reviews the operating principle of the acousto-optic tunable filter (AOTF) and describes some of the recent progress. A ray tracing algorithm was derived that was used to determine the image aberration due to the AOTF. The calculated result is compared with the experimental result of the AOTF configured as an electronically tuned imaging spectrometer. Due to the recent progress of AOTF technology, a wideband (10 nm) visible AOTF with a one inch aperture is now realizable.
