Abstract本发明涉及一种超灵敏时间分辨光谱仪,包括:光学单元和电学单元,其中,光学单元包括入射狭缝、光准直部件、凹面镜、光栅分光部件、空间光调制器以及会聚收光部件;凹面镜包括第一凹面镜和第二凹面镜;电学单元包括随机数发生器、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;待测极弱光经由入射狭缝入射,通过光准直部件和第一凹面镜做扩束和准直,成为平行光;平行光照射到光栅分光部件;所生成的光谱场经过第二凹面镜反射,在空间光调制器上展开成光谱带;空间光调制器对光谱带进行随机调制,使得其出射光以一定的随机概率向会聚收光部件反射;会聚收光部件滤除杂散光,将过滤后的光传输到单光子点探测器。
