| 摘 要： | 使用基于非线性最小二乘法的方法处理扫速标定数据，获得了条纹相机的全屏扫速数据，消除了扫速非线性和空间畸变对测量结果的影响。该方法的不确定度约为0.04%，远小于条纹相机的系统误差。利用该方法得到了各个像素对应的扫速，其不确定度约为1.5%，显著减小了条纹相机测量结果的误差。

| Abstract: | The result of full-screen sweeping rates of streak camera(SC) is obtained using a nonlinear-least-squares method. The uncertainty of this method is about 0.04%, far below SC’s systematic uncertainty. Full-screen result eliminates nonlinearity and space-distortion of sweeping rates, minimizes the error of SC’s measurement to about 1.5%. The robustness and time-efficiency of this method make full-screen calibration of time-domain and space-domain feasible． |
