Detector	Advantage	Disadvantage	Scene for use
PIN-PD	Fast response speed, lower cost, good resistance to ambient light and unity gain	Thermal noise and difficult trade-off between response speed and quantum efficiency	Short-wavelength scene
APD	Long response time , higher internal gain than that of PIN-PD, and high quantum efficiency	High bias voltage, complex control circuit, sensitivity to environmental noise, and shot noise limitation	Long-wave receivers, long-distance transmission and high-rate systems
PMT	High sensitivity, high frequency response, high gain, low noise and large collection area	Large size, large power consumption, bad overexposure tolerance, vulnerability in shock and vibration, and high cost	Static link
