基于CIS的瞬态信息分幅成像技术
Framing imaging technology for transient information detecting based on CIS
摘要
Abstract
Microchannel plate(MCP)traveling-wave gated framing cameras are widely used for inertial confinement fusion.However,they suffer from drawbacks such as bulky size and non-single-line-of-sight imaging.To address these limitations,a complementary metal oxide semiconductor(CMOS)image sensor(CIS)is proposed as an alternative to MCP image converter tubes.Based on a 0.18 μm standard CMOS process,an 8×8 pixel array CIS architecture is designed.An ultrashort shutter pixel circuit together with a dedicated shutter signal control circuit is developed to realize single-shot four-frame imaging.In addition,a correlated dual-sampling circuit based on a single-ended amplifier is employed to effectively suppress noise.Simulation results indicate that the proposed circuit operates properly,and the pixel signal uniformity of the four captured frames exceeds 99%,with a temporal resolution of 100 ps per frame and an inter-frame interval of 300 ps.关键词
