针对红外成像制导装置箱内贮存的光学性能标定检测,以及其全生命周期的寿命评估和预测需求,提出了基于复眼阵列逆合成孔径成像的阵地检测新原理,利用每一个透镜单元所承担的光束孔径共同构成检测系统的出瞳,实现了红外平行光模拟检测装置的超薄化、贮存箱内嵌入式设计,研制了大出瞳直径、短焦红外制导装置箱内检测系统样机,并通过中波热像仪进行了成像像质验证,为降低导弹阵地关键光学参数检测的技术准备时间和综合检测成本、控制检测风险提供了技术支持。

Aiming at the calibration and testing of the infrared imaging guidance device’s optical performance in the storage period,as well as the requirements of the life assessment and prediction in the full-life-cycle,this paper proposes a new position testing technology based on the inverse synthetic aperture imaging principle using the compound eyes array.The pupil of the testing system is composed of the beams’aperture of each lens unit and the ultra-thin parallel infrared light simulation testing device is available in the storage tank by the embedded design.With a large pupil diameter and short focus,the prototype of an embedded testing system for infrared guidance device is developed and the imaging quality is verified by a midium wave infrared radiation(MWIR)imager.It provides a technical support for the missile’s key optical parameters position testing in saving the technical preparation time,reducing the comprehen sive testing cost and avoiding the testing risk.
