Paper Abstract

Optical instruments usually use optical transfer functions to represent the target image quality. It can represent the spatial characteristics of the imaging spectrometer and the transmission characteristics of signal output and input in the frequency. However, for the imaging spectrum instrument, it can obtain both the spectral and spatial information at the same time, so it is also necessary to use the spectral transfer function to represent the spectral characteristics of the imaging spectrometer. In this paper, first, the working principle of double AOTF imaging spectrometer was introduced. Second, the spectral transfer function of double AOTF imaging spectrometer acoustics optic crystals was established. It is obtained by integrating the spectral transmission function within the wave difference range when the wave number difference is greater than zero. Last, the spectral transfer function in the 400nm-900nm of double AOTF imaging spectrometer acoustic optic crystals with the central wave difference and same were calculated. The results show that the wavelength difference was higher than that of the small spectral transfer function.The research results of this paper provided reference for the design and research for new imaging spectrometer.
