      according to the special airframe construction of the prototype and the particular environment of the near space, the thermodynamics modeling simulation is designed to instruct the temperature-rise tests on the ground and guarantee the steady operation of the optics, electronics and mechanical structure system in optical transmitter and receiver, which demonstrated the goodness of fit for theoretical and experimental analysis. in the meantime, the temperature-rise tests for the critical components and physical model are controlled by bp algorithm which saved experimental periods and improved the conventional efficient. in the end, the internal temperature field distribution in the optical transmitter and receiver is analyzed in this paper, and how to keep the uniformity of the thermal field in a short time is studied as well. and the analytic results show that the experiments satisfy the required indices, what’s more, the analytic process may supervise the analytical calculation of the same type optical transmitter and receiver, which is worth using in engineering.
