The aero-optical effects generated by the high temperature shockwave flow field around the head of infrared guided hypervelocity flight vehicles will seriously influence the detection, identification and tracking. In order to correct this, some photoelectric correction technologies on aero-optical effects are discussed. Main subjects are adaptive optics technology based on wave-front sensing and self-focusing, compact photoelectric systems with high frequency, frame frequency and frame integrating time of image adaptively varying technology and phase diversity technology. Comparative analysis is also presented on the photoelectric correction technologies mentioned above.
