摘要	Imaging spectrometers for atmospheric detection usually split the beam by using prisms or gratings. However, owing to their spectroscopic principle, these spectrometers can only detect the atmosphere via single mode and single detection. The acousto-optic tunable filter (AOTF) is an electronic filter developed based on the acousto optic effect of crystal with a field of view that is not limited by the slit. This paper introduces the spectroscopic principle of the AOTF and deduces its diffraction equation. By using the AOTF as a spectroscopic device, this paper also designs a new imaging spectrometer for atmospheric detection. This spectrometer has two fields of view and can detect the hyperspectral atmospheric data in 10 degrees nadir field of view, 360 degrees limb field of view, and 0 km to 100km limb height. The optical system of this imaging spectrometer comprises a front objective lens, an AOTF spectroscopic system, and a relay lens. As an instrument for atmospheric, this spectrometer has the characteristics of dual observation modes, full coverage in the limb field of view, and high spectral resolution.
