【摘要】 采用红外成像寻的精确制导体制的高速飞行器在大气中以高超音速飞行时,头罩周围的高温激波流场将产生气动光学效应,这种效应严重影响了导引头对目标的探测、识别与跟踪,必须对此采取措施进行校正。文中介绍了气动光学效应的光电校正方法,包括基于波前检测与基于像清晰化校正以及高频微型光电子校正等自适应光学校正、图像帧频与帧积分时间自适应变化校正和光学与图像处理综合校正等方法,并对各种方法进行了比较分析。更多还原

【Abstract】 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.更多还原
