    Abstract

    Aiming at the influence of the aerodynamic heating effect of the high-speed vehicle on the optical performance of the vehicle, the heat radiation model of the dome window of the vehicle was established. On this basis, the simulation control program was programmed, and the optical automatic tracing was realized by using TracePro software, and the thermal effect of the dome window produced during the scanning of the entire optical system, as well as the effects of individual optical moving parts when scanned separately were dynamically simulated. Through the analysis of the transmission path of stray light caused by thermal effect in the process of rosette scanning, the proposed improvement measures were obtained, which provided a reference for the optical performance analysis and environmental failure research of high-speed vehicle.
