AOTF has become an important dispersive device in the field of deep-space remote sensing because of its characteristics such as small size, light weight. For the purpose of developing a method to obtain high-precision spectral inversion data from SWIR spectrometer based on AOTF under the condition of wide temperature range in deep-space exploration, firstly, the principle of AOTF, as well as the configuration of SWIR spectrometer based on AOTF were introduced. Then, the temperature effect on AOTF, RF amplifier and InGaAs detector with TEC in the spectrometer was analyzed theoretically. Through the temperature simulation experiment, a date pre-processing model for temperature effect correction was set up and validated finally, which provided a guarantee for acquiring high-accuracy data in deep-space exploration application.
