    • PROBLEM TO BE SOLVED: To solve a problem of a single photon detector, where a signal output by the detection of a single photon is often weak and, in some cases, it is difficult to discriminate it from another artifact output from the detector.SOLUTION: A photon detection system includes: a photon detector (APD 51) configured to detect single photons; a signal divider (a power distributor 55) to divide the output signal of the photon detector into a first part and a second part, where the first part is substantially identical to the second part; a delay means (a delay line 56) to delay the second part with respect to the first part; and a combiner (a hybrid coupler 61) to combine the first part and the delayed second part of the signal such that the delayed second part is used to cancel periodic variations in the first part of the output signal.

A photo-detecting device having a magnetic shielding tube and a safety window includes a photo-multiplier tube(11) as a photo-detector.
