通过采用各向异性聚焦及电四极透镜技术,设计出物理弥散达到0.38ps,边缘空间分辨力达到56lp/mm的新型条纹变像管。研制出对条纹相机高压输出、环境监测、扫描档位切换和相机工作方式选择的模块化程控系统。利用Nd:YLF(脉冲宽度8ps、波长263nm)脉冲激光器对相机的性能指标进行了标定,测得静态和动态空间分辨力分别为35lp/mm和25lp/mm,动态范围达到950∶1,时间分辨力达到8ps,在扫描和狭缝方向可实现独立变倍和KB显微镜耦合,便于对目标的空间分辨力进行灵活配置。
Through the use of anisotropic focusing and electric quadrupole lens technology, a new streak tube with a physical dispersion of 0.38ps and an edge spatial resolution of 56lp / mm was designed. Developed a modular programmable control system for high-voltage output of streak camera, environmental monitoring, switching of scan gear and camera selection. The performance of the camera was calibrated using a pulsed Nd: YLF laser with a pulse width of 8ps and a wavelength of 263nm. The static and dynamic spatial resolutions were 35lp / mm and 25lp / mm, respectively, and the dynamic range was 950: 1. Force up to 8ps, in the scanning and slit direction can be achieved independent zoom and KB microscope coupling, easy to configure the spatial resolution of the target.
