摘要

介绍了一种以氮分子激光器作光源的ＣＣＤ相机阴影照相系统，该系统能可靠地对高速运动目标和瞬变现象进行阴影照相电子成像，并提出了基于该系统的阴影照相电子成像测速法．该系统具有一些独到的优点：作为系统光源的氮分子激光器的脉宽为纳秒量级（火花光源的脉宽为微秒或亚微秒量级），适用于高速摄影；对环境无特殊要求，能在一般室内环境下正常工作；电子成像技术的采用，使得该系统无需显、定影及判读等操作，直接由计算机进行图像处理和输出．

Abstract

In this paper

a CCD camera shadowgraph system with nitrogen molecule laser light source is mentioned to get the shadow image of moving objects. The way on velocity measurement of moving object is also mentioned. The system is suitable for highspeed photography and can work at normal environment. More importantly

the picture or the data that we can be got directly through the computer or the camera

needing not film development and fixing which are necessary for the traditional photography.
