摘要: 为了解决百ns级可见光条纹相机时空非线性标定需求，提出了通过构建一个时空二维分布的等间距标准光场快速标定条纹相机二维非线性的设想。通过序列脉冲光构造技术获得时间维度间距相等的参考点；通过光场空间调制技术获得空间维度间距相等的参考点。分析了序列脉冲光和光学系统的设计准则，基于该准则研制了一套可见光条纹相机二维非线性快速标定系统。该系统的时间分辨可达0.1 ns、空间分辨小于90 μm。基于该系统，通过单次扫描成像高效标定了国产某型条纹相机的扫描非线性、时间弥散、时间畸变和几何像差等非线性信息。此外，利用该系统对不同电路的扫描非线性进行了分析验证。该标定系统快速验证了双边扫描电路有利于优化扫描非线性。分析验证结果表明，该标定技术通过单次扫描即可对条纹相机的非线性参数进行标定。Abstract: To resolve the calibration of temporal and spatial nonlinearity of an optical streak camera in 100-nanosecond level, an idea of rapid calibration of two-dimensional nonlinearity of optical streak camera has been proposed with the method of constructing an equidistant standard light field in the temporal and spatial dimension. The reference points with equal spacing of temporal dimensions have been obtained by the technique of sequential pulsed light construction. In addition, the reference points with equal spacing of spatial dimensions have been obtained by the spatial modulation technique of light field. The design criteria of sequential pulsed light and optical system have been analyzed. Based on the criteria, a high-performance system to calibrate two-dimensional nonlinearity of optical streak camera has been developed. The temporal resolution of the system is 0.1 ns and the spatial resolution is less than 90 μm. Based on the system, the sweeping nonlinearity, time dispersion, temporal distortion and geometric aberration of a domestic streak camera have been calibrated quickly via a single sweeping image. In addition, the sweeping nonlinearity of different circuits has been analyzed and verified by the system. The calibration system quickly verified that the double-sided scanning circuit was conducive to optimizing the scanning nonlinearity. The analysis and verification results show that the calibration technology could calibrate the nonlinear parameters of a streak camera via a single sweeping image.
