Research of an ultra-fast CMOS image sensor for four-frame imaging

A four-frame imaging ultra-fast CMOS image sensor for inertial confinement fusion diagnosis is studied. Based on the 0.18 μm standard CMOS technology, the design and simulation of the CMOS image sensor are completed. And the logic reliability of the CMOS imaging sensor based on the in situ pixel division scheme is simulated and verified. The simulation results show that the CMOS image sensor can capture four images at a time, and the time resolution of each image could be controlled at about 300 ps, the frames interval between two adjacent images could be controlled at about 600 ps.
