Paper Abstract

Combined with two-channel one-dimensional field of view imaging technique and Spatial Heterodyne Spectroscopy (SHS), hyper-resolution spatial heterodyne spectrometer can be used for hydroxyl radical OH detection with limb observations from a satellite. The accuracy of field registration of the spectrometer two channel directly affects the detection accuracy of hydroxyl radical OH density, and the spatial stop and spectral stop of each channel are in different positions on the path of light. The method of spatial and spectral dimension field registration is given first, and then the method of field of view registration between channels is given. The quantitative effect of the parameters of the registration method on the accuracy of the field registration is analyzed theoretically, and the verification test is carried out based on the long focal length collimator. The results show that the accuracy of field of view registration in this paper is better than 99.2%. It provides a theoretical basis for the tolerance of the spatial field of view of the spectrometer.
