In recent years,the demand for optical imaging and detection in hypersonic aircraft has been on the rise.The high-temperature and high-pressure compressed flow field near airborne optoelectronic devices creates significant interference with light transmission,known as hypersonic aero-optical effects.This effect has emerged as a key technological challenge,limiting hypersonic optical imaging and detection capabilities.This article focuses on introducing the thermal effects and optical transmission effects of hypersonic aero-optical effects,as along with corresponding suppression techniques.In addition,this article critically reviews and succinctly summarizes the advancements made in hypersonic aero-optical effects testing technology,while also delineating avenues for future research needs in this field.In conclusion,there is an urgent call for further exploration into the study of aero-optical effects under conditions characterized by high Mach,high enthalpy,and high Reynolds number in the future.
