Abstract Of all the hyperspectral imaging system using the optical filtering elements available,. AOTF(Acousto-optic tunable filters) is best to choose a filtering optical element that has high-speed spectral selectivity with high resolution, it can greatly reduces the amount of data collection and processing. In this paper , First, the work principle of AOTF was introduced, then described the AOTF imaging system, it covers the spectral band from 400nm to 900nm with a spectral resolution of near 2nm at 400nm and 10nm at 900nm. The device can provide about 2.2° view field angle and 10mm aperture, which included TeO2 crystal, image optical system, a charged coupled device(CCD)camera, rf electronics and control and processing software. Finally the paper presented the results of laboratory image testing.
