The calculation method of the optical transmission components of the laminar flow field in the aerodynamic optical transmission is studied. The image migration caused by the laminar flow field and the low degree of image ambiguity are studied by ray tracing and physical optics. Combining with the flow field under typical conditions, Data, the mathematical simulation of the optical transmission effect of the high-speed laminar flow field was carried out, and the simulation results were obtained. Comparing the calculated results with those obtained by engineering calculation, the calculated flow field data are used to prove that the theoretical model of the optical transmission effect of the aerodynamic optical high-speed flow field is basically correct and can be used for the simulation calculation.
