摘要：

An improved Time-Correlated Single Photon Counting (TCSPC) technique features high count rate, low differential nonlinearity and multi-detector capability. The system has four completely parallel TCSPC channels and achieves an effective overall count rate of 20 MHz. By an active routing technique, up to eight detectors can be connected to each of the TCSPC channels. We used the system to record optical mammograms after pulsed laser illumination at different wavelengths and projection angles.
