Aero-optical effects have received increasing attention in recent decades with the
continuous development of high-speed missiles' imaging guidance systems, airborne laser …

USUALLY, the forepart of an optical-guided vehicle is generally composed of the body with
a dome or hood shape and the optical window to seek a target. The aero-optical window of a …

Optical imaging detection is an important research direction in the precision guide field. The
quality of observation would be profoundly deteriorated due to the aberration, jitter, and …
