为了实现对“弱、小、多、快”目标的跟踪测量,我们研制了一种选通象增强高速电影摄影系统。它是集激光象增强技术、激光照明技术、电子选通技术及高速电影摄影技术于一体的新型系统,它具有光增益高,成象质量好,可探测距离远等特点。 该系统采用了带选通的二代象增强器;采用了电子快门,其曝光时间在1μs—300μs可调,频率在1—100帧/秒可调;采用了非透镜耦合的方式,解决了胶片与耦合面板之间的静电放电问题,以及高速运转时它们之间的磨擦问题,采用了小数值孔径耦合面板,改善了耦合分辨率,采用了高性能的间歇输片机构,实现了胶片的高速间歇运动。 本文还介绍了该系统的静态和动态测试结果,以及在激光照明下的测试结果。
In order to achieve the “weak, small, multi, fast” tracking of the target, we have developed a gated elephant enhanced high-speed movie photography system. It is a new system integrating laser enhancement technology, laser lighting technology, electronic gating technology and high-speed movie photography technology. It features high optical gain, good image quality and long detection range. The system uses a gated second generation image enhancer; the use of electronic shutter, the exposure time of 1μs-300μs adjustable, the frequency of 1-100 frames / second adjustable; using a non-lens coupling to solve the Electrostatic discharge between the film and the coupling panel, as well as the friction between them at high speed, the use of a small numerical aperture coupling panel to improve the coupling resolution, the use of high-performance intermittent film transfer mechanism to achieve the film’s High-speed intermittent exercise. This article also describes the system’s static and dynamic test results, as well as laser lighting test results.
