Abstract

With the development of astrophysics, the astrophysics demands are higher and higher. Astronomical spectral polarization observation can obtain more object information to provide comprehensive data for further research. A polarization imaging spectrometer based on acousto-optic tunable filter was developed for ground-based telescope, which can obtain the image spectral polarization information at the same time. In this paper , first, the work principle of AOTF was introduced, then described the AOTF imaging system for ground-based astronomical observation，it covers the spectral band from 450nm to 900nm . The device can provide about 3.6° 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 optical design.
