微光像增强器是夜视领域重要的光电探测和成像器件，它在头戴显示、手持观测和夜间瞄准等方面应用广泛。带有光纤倒像器的超二代倒像式微光像增强器在夜间瞄准系统中应用较为广泛，根据实际应用需求情况，分析倒像式微光像增强器像固有误差中翻转角误差和蛇形畸变对应用中瞄准、行程差测量误差的影响。通过分析说明，像翻转角误差小于30'，蛇形畸变小于30 μm时能够满足中近程瞄准和行程差测量的需求，并研制了检测装置对其误差进行质量控制，解决该问题的同时对该类应用的像增强器生产制造提出了相关质控点。
Abstract
The low-level-light image intensifier is an important photoelectric detection and imaging device in the field of night vision, and it is widely used in head-mounted display, hand-held observation and night aiming. The super-second-generation inverted image low-level-light image intensifier with fiber-optic image inverter is widely used in the night aiming system. According to the requirement of practical application, the influence of turning angle error and snake-shaped distortion in the inherent error of inverted image low-level-light image intensifier on the measurement error of aiming and stroke difference in application was analyzed. The analyses show that when the image turning angle error is less than 30' and the snake distortion is less than 30 μm, it can meet the requirements of close-range aiming and measurement of stroke difference. A detection device was developed to control the error, which solved the problem and put forward the relevant quality control points for the production and manufacture of image intensifiers for this kind of application.
