Photon counting and its application

"The photon counting methodology is relatively complicated, because the energy of a single photon in optical radiation is very small - in the order of 10- 19 J. Good knowledge and experience are required to single out such a portion of energy from electrical noise in the photodetector and associated electrical equipment, and to multiply it to the level required for digital electronic devices. For this reason, the photon counting methodology has not yet emerged from research laboratories as a standard method that can be widely used by any employee to measure weak optical radiation. Therefore, this material describes the author's many years of experience in the development of photon counting methodology and its use in measuring weak and rapidly changing optical radiation fluxes, so that the reader can gain knowledge about photon counting from the author's experience."
