Abstract:
    A photon counter bases on program logic for photoelectric information in faintness photoelectric information dispose technology. It relates to impulse amplify circuit, impulse discriminate circuit, impulse plastic circuit, controlling circuit for counting door and photoelectric counting circuit. The circuit of amplify, discriminate and plastic realize the magnifying of faintness photoelectric current, the identifying of impulse signal and the plastic of wave and realize the join with the hardware circuit of program logic (PLD). Its character is that PLD realizes the design of photons counting circuit and controlling circuit for counting door. The photons counting circuit uses for photons counting, numerical value lock and store and output, and the controlling circuit for counting door controls the counting time of photons counting circuit and its counting time is adjustable, automatically recorded into set time and repeated to count time.
