We propose and demonstrate a photon-efficient optical classifier to overcome the Rayleigh limit in spatial resolution. It utilizes mode-selective sum-frequency generation and single-pixel photon detection to resolve closely spaced incoherent sources based on photon counting statistics. Super-resolving and photon efficient, this technique can find applications in microscopy, light detection and ranging, and astrophysics.
我们提出并演示了一种光子效率高的光学分类器，以克服空间分辨率中的瑞利极限。它利用模式选择性和频产生以及单像素光子检测，基于光子计数统计来分辨间距紧密的非相干光源。这种超分辨且光子效率高的技术可应用于显微镜、光探测与测距以及天体物理学领域。
