Abstract本发明涉及超灵敏时间分辨成像光谱仪,包括光学单元和电学单元,光学单元包括入射狭缝、光扩束准直部件、光学成像部件、第一和第二空间光调制器、凹面镜、光栅分光部件、会聚收光部件;电学单元包括第一和第二随机数发生器、单光子点探测器、计数器、时间测量仪、控制模块、数据包存储器以及压缩感知模块;待测极弱光入射,经光扩束准直部件变成平行光,透过光学成像部件成像在第一空间光调制器上;第一空间光调制器做随机调制;凹面镜将入射光反射并准直,变成平行光,打向光栅分光部件形成光谱场,在第二空间光调制器上形成光谱带;第二空间光调制器对光谱带做随机调制;会聚收光部件滤除杂散光,过滤后的光传输到单光子点探测器。
