用非校准线性光电探测器进行光统计
Light statistics by non-calibrated linear photodetectors
摘要:
我们从理论上证明,具有内部增益的探测器,并在制度中,他们不一定表现为光子计数器,但仍然确保线性输入/输出响应,可以允许一个自洽的表征所检测到的光子的数量的统计,而不需要知道他们的增益。我们目前的实验与光电混合探测器上的一些经典领域赋予非平凡的统计,并表明该方法适用于微观和介观光子数。得到的探测光子的概率分布与预期的光子数,这也是由一个独立的方法重建。
英文摘要:
We theoretically demonstrate that detectors endowed with internal gain and operated in regimes in which they do not necessarily behave as photon-counters, but still ensure linear input/output responses, can allow a self-consistent characterization of the statistics of the number of detected photons without need of knowing their gain. We present experiments performed with a photo-emissive hybrid detector on a number of classical fields endowed with non-trivial statistics and show that the method works for both microscopic and mesoscopic photon numbers. The obtained detected-photon probability distributions agree with those expected for the photon numbers, which are also reconstructed by an independent method.
