  • Measuring distance with light | Hamamatsu Photonics

    In any light detection application, the lower limit of signal detection is determined by the noise characteristics of the detector and its amplifiers. There are three primary sources of noise in any optical detector system: photon-related shot noise, detector dark noise, and amplifier noise. The first two are related to the detector.
