How Are Photons Detected. Effectively, less than 10 percent of the photons that hit the cornea make it to the rod cells in the retina, which result in nerve signals that travel into the brain, causing perception. Photons incident on the tube create an avalanche of electrons in each stage that can be. Physicists, however, have now devised a way to detect single photons of visible light without bringing about their demise. Its momentum is decided precisely and it means. It seems possible to detect a single photon.[1, 2] but the photon is a free particle. Detect enough photons and you can infer the center of the beam profile (with precision that depends on noise and how many photons. One way of measuring single photons is to use a photomultiplier tube.
