光学条纹相机扫描速度和非线性的测试

Measuring sweep speed and sweep nonlinearity of optic streak camera

介绍了光学条纹相机的扫描速度测试实验和非线性计算过程以及结构、工作原理,并讲述了实验是以YAG染料激光器为光源,利用标准具的精确距离得到相机所测条纹图上相邻两条纹之间的时间间隔,以此推算条纹相机的扫描速度,并用重复测量的方法推算出相机的扫速非线性。

An experiment of measuring the sweep speed of an optic streak camera and the process of calculating the nonlinear are mostly discussed in this thesis. The structure and the working principle of the optic streak camera also are introduced. An YAG dye laser is used as light source, and the exactitude distance of an etalon is used to obtain the interval of two adjacent streaks in the acquired streak image by the camera. So the sweep speed(ps/ch) of the camera can be calculated by that. The nonlinear of the sweep speed of the camera is calculated by the way of repetitive measuring.
