    In order to obtain more implosion movement information of inertial confinement fusion and measure the temporal-spatial characteristics of plasma during fusion combustion phase, the framing tube was studied whose exposure time was better than 30 ps, using electron beam pulse-dilation and composite lenses imaging technology. The reason of performance difference between two tubes was analyzed through the tubes structure, working principle and measurement. The study result shows that the MCP gated framing tube has better spatial resolution performance and the new framing tube has more excellent temporal resolution performance. The spatial resolution and exposure time of MCP gated framing tube is ~53 μm(the modulation is 4%) and 97 ps, respectively. And, the new framing tube is ~74 μm(the modulation is 3%) and 21 ps, respectively. The mass reliable data is provided to study inertial confinement fusion through the high temporal resolution framing imaging technology.
