Abstract

We describe the construction and performance of an acousto- optic tunable filter (AOTF) camera system for obtaining images in the range of 450 to 1000 nm. A combination of a 10-bit digital video camera and a high speed frame grabber board allows continuous display of high-resolution, filtered images on a computer monitor at 30 frames per second. Ability for target recognition is significantly enhanced by processing filtered images. A typical speed in a basic operation that requires two frame grabs at two different filter settings and image processing is currently limited to 6 frames per second. The pre-processing of the target image by the AOTF simplifies subsequent image processing and is nearly real time.
