Abstract: An asymmetric spatial aberration wind measurement interferometer is designed to simultaneously detect 557.7 nm oxygen-atom green-line airglow and 630.0 nm oxygen-atom red-line airglow in the detection range of 90-300 km according to the needs of wind field detection in the middle and upper atmosphere, and the optical range difference compatible with the two bands is selected according to the relationship between the interferometric fringe modulation regime and the optimal optical range difference for the detection of the two bands. The field of view of the interferometer is improved by designing and selecting the top angle and material of the expanded field of view prism. In order to reduce the influence of thermal deviation on the accuracy of wind measurement, the relationship equations between thermal deviation and shim material, shim thickness, and interferometer bias are derived, and the corresponding parameters are calculated by this equation. In addition, a middle-step grating is adopted as the reflection grating to realize the simultaneous detection of dual-band. According to the needs of the foundation detection, the required front lens group and rear lens group are designed. Finally, the overall system is simulated and the simulated streak map is obtained to verify whether it meets the needs of dual-band detection. The thermal deviation of the optical range difference of the final interferometer in the 557.7 nm airglow band is 3.22×10⁻⁶ mm/°C, and the phase thermal drift is 0.03 rad/°C. The thermal deviation of the optical range difference in the 630 nm airglow band is 9.45×10⁻⁷ mm/°C, and the phase thermal drift is 0.00942 rad/°C. The design results show that the system is suitable for dual-band detection. The design results show that the system meets the need for 90-300 km wind measurement and reduces the influence of thermal deviation on the measurement accuracy compared with the earlier design.
