| Abstract: | The mathematical model of light beam transmission across the optical widows in the aerodynamic thermal environment was built using the method of the finite element analysis and optical design.The optic transmission theory and computational method were studied.The influence of the optical window with non-uniform index to the object imaging was analyzed through the ray-tracing program.The programming result indicates that the ray-tracing program of optical window is feasible.The research is useful for the successive imaging work. |
