摘要

The increase in aircraft flight speed has increased the opportunities for high-speed optical aperture applications. However, due to the influence of aero-optical effects, the light beam can appear offset, jittering, blurring, and suffer energy attenuation, all of which affect the optical quality. In the current paper, we summarized the key research progress on the fluid dynamics and aero-optical effects of high-speed optical apertures. The influence of the flight state and optical parameters on the aero-optical effects was analyzed and described. Moreover, we evaluated potential aero-optical suppression solutions, such as flow control and adaptive optics. This work provides useful guidance and aid to scholars engaged in research on the high-speed aero-optical effects.
