我们实验表征的性能的电子倍增电荷耦合器件（EMCCD）相机的单光子探测。测试是用参量下转换（PDC）产生的光子对完成的。分析了EMCCD的增益、时间响应和噪声特性。此外，我们尝试使用相机来测量PDC的空间相关性。结果揭示了EMCCD作为单光子探测器阵列在量子光学、天文学和显微学应用中的能力和局限性。
We experimentally characterize the performance of the electron multiplying charge-coupled device (EMCCD) camera for the detection of single photons. The tests are done with the photon pairs generated from parametric downconversion (PDC). The gain, time response and noise performance of the EMCCD are characterized. In addition, we attempt to use the camera to measure the spatial correlations of PDC. The results reveal the capabilities and limits of the EMCCD as a single-photon-detector array for the applications of quantum optics, astronomy and microscopy.
