Abstract: 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.
