论文摘要
我们描述了一个快速数据驱动的光学摄像头TPX3CAM,并具有纳秒刻度计时分辨率和80 mpixel/sec吞吐量。添加增强剂后,摄像机对单个光子敏感,其量子效率主要由增强剂光电极确定。相机的单个光子性能的特征是在此报告的增益,时机分辨率和后螺栓的结果。加强的摄像头成功用于包括量子应用在内的多种应用中的测量。作为需要同时检测多个光子的这种应用的一个示例,我们描述了光谱仪中自发参数下转换源的光子对的注册。我们以0.15〜nm和3〜ns的精度测量了光子波长和时序,并且还证明了两个光子在能量上是抗相关的。
We describe a fast data-driven optical camera, Tpx3Cam, with nanosecond scale timing resolution and 80 Mpixel/sec throughput. After the addition of intensifier, the camera is single photon sensitive with quantum efficiency determined primarily by the intensifier photocathode. The single photon performance of the camera was characterized with results on the gain, timing resolution and afterpulsing reported here. The intensified camera was successfully used for measurements in a variety of applications including quantum applications. As an example of such application, which requires simultaneous detection of multiple photons, we describe registration of photon pairs from the spontaneous parametric down-conversion source in a spectrometer. We measured the photon wavelength and timing with respective precisions of 0.15~nm and 3~ns, and also demonstrated that the two photons are anti-correlated in energy.
