Abstract

In order to obtain multispectral imaging system and enhance the performance of acousto-optic tunable filter AOTF, Rotary polarization technique was used in the AOTF designing. According to spectral bandwidth, acousto-optic figure of merit, acoustic frequency spectral range, the polar angle for incident and diffracted beams ware optimized. Spectral and spectral imaging on rang of 400-800nm ware acquired.
