摘要
利用多个线阵CCD(Charge Coupled Device)组建成测量高速运动目标运动参数及记录运动姿态的系统,通过两两CCD进行组合可以测出多个速度值,并可以通过还原弹型图像的方法进行测时修正。对测试系统和测时仪进行了原理设计,举例进行了测速仿真,结果表明:本方法具有较高的测速精度。
The system composed with multi-linear-CCD array can test the parameters of high speed object and take photos of attitute of the high speed object. Multistage speed is measured by two random linear CARD, and the speed could be corrected by measuring high speed linear CArD picture. This paper describes the design of the test system, chronograph and speed test simulation. Simulation result indicates that the method is doable.
