Abstract本发明涉及一种超灵敏光谱仪,包括光学单元和电学单元;光学单元包括入射狭缝、光准直部件、凹面镜、光栅分光部件、空间光调制器、会聚收光部件;凹面镜包括第一凹面镜,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、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,然后通过光准直部件和第一凹面镜做扩束和准直,使之成为平行光;平行光照射到光栅分光部件生成光栅反射光场,再经过第二凹面镜反射,在空间光调制器上展开形成光谱带;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发射;会聚收光部件滤除杂散光,将过滤后的光传输到电学单元中的单光子点探测器。
