随着惯性约束聚变研究的深入发展，对高精密诊断设备的要求越来越高，基于半导体材料的光致折射率变化这一特性，对新型高时间分辨的全光扫描技术进行了深入研究。重点介绍了影响光扫描模块偏转特性的两大关键技术，即光扫描模块的设计以及泵浦光与信号光时间同步。通过分解实验开展验证性研究，结果表明：通过前期设计制作的光扫描模块可较好地应用于实验中，在一定范围内，泵浦光功率密度越大信号光的偏转也就越大。同时，时间同步对信号光的偏转程度影响也较大，即高时间同步关系也决定了光扫描装置的时间分辨率。

The studies of inertial confinement fusion (ICF) propose increasing demands for high precision detection devices. This paper is mainly about the studies on a novel optical streak camera with ultrahigh time resolution based on the photo-generated carrier effects, in which the key technology, the design of the optical scanning module and the temporal synchronization between the pump light and the signal light, will deeply influence the performance of the optical scanning module. The experimental results show that the deflection of the signal light increases with the power density of the pump light, which confirms the feasibility of the designed optical scanning module. The temporal synchronization will also influence the deflection of the signal light, which means that the temporal synchronization will finally determine the temporal resolution of the optical scanning device. The studies in this paper can well support the next studies on the time-to-space conversion of ultra-short signal light.
