Summary: | The present invention relates to a three-dimensional imaging photon counting system using N-fold pulse coding and a counting method. The system includes a total controller, a signal generator, a pulselaser, a transmission optical system, a receiving optical system, a Gm-APD array detector, and a TCSPC (time-correlated single photon counter) and a signal processing unit. According to the method ofthe present invention, the total controller controls the signal generator to generate N-fold pulse signals; the N-fold pulse signals are converted into pulse optical signals through the pulsed laser;thee pulse optical signals hit a target object through the transmission optical system; the energy of echo pulse signals reflected by the target object is collected by the receiving optical system; the echo pulse signals irradiate the Gm-APD array detector; signals generated by the detector pass through the TCSPC (time-correlated single photon counter); counted signals are transmitted to the signal processing unit for time |
