| 摘 要： | 对相机全屏扫速性能进行了系统分析，发现基于相机整体的平均扫速及扫速非线性处理扫描时间的传统方法不能反映相机空间畸变现象，并且扫速非线性放大了数据处理不确定度，从而降低了相机应用价值。建立了一套基于全屏扫速及扫速不确定度的扫描时间精细处理方法，它自洽消除了相机的空间畸变和扫速非线性的系统性影响。开展了理论分析和验证实验，结果表明:精细处理方法很容易使扫描时间数据处理相对不确定度降低到1%以内，显著提高了条纹相机时间扫描精度和应用可靠性。

| Abstract: | The sweep time performance of the optic streak camera(OSC) is of critical importance to its application. The systematic analysis of full-screen sweep velocity shows that the traditional method based on the averaged velocity and its nonlinearity would increase the uncertainty of sweep time and can not reflect the influence of the spatial distortion of OSC. A elaborate method for sweep time has been developed with the aid of full-screen sweep velocity and its uncertainty. It is proved by the theoretical analysis and experimental study that the method would decrease the uncertainty of sweep time within 1%, which would improve the accuracy of sweep time and the reliability of OSC application. |
