针对热释电摄象管(PEV)在传统的对称斩波模式下存在的各种问题,设计了一种新的非对称斩波模式PEV红外电视系统.通过提高PEV摄象机的温度响应率R_i和采用高去噪声信号处理系统,大大改善了PEV红外成象系统的性能.
A new type PEV infrared TV system in an asymmetrically chopped mode opera- tion is designed in order to solve the problems in the standard chopped mode operation. By increasing the temperature responsivity R_i and adopting a high signal-to-noise ratio processor, the performances of the PEV infrared imaging system have been improved great- ly.
