Objectives Due to the high sensitivity of the singlephoton detector, an ultranarrow band filter is needed to ensure the normal operation of the detector under the influence of strong background light noise in the daytime. Therefore, the antibackground noise ability of photon heterodyne detection is crucial. In addition, the dark count and postpulse effect of the singlephoton detector will lead to a false count and thus reduce the signaltonoise ratio (SNR). Therefore, new methods are required to improve the SNR of photon heterodyne detection. In the earlier research on photon heterodyne detection, most scholars focused on signal processing for denoising. They proposed new signal processing methods to denoise echo signals and rarely made an effort to improve the detection system or change the photon counting mode. As current signal

The singlephoton detection technique has unique advantages, such as high sensitivity, low timing jitter, and low power consumption. Thus, its applications in laser ranging and imaging are becoming increasingly widespread. In this paper, we introduce a lowcost highprecision singlephoton ranging system, in which a narrow pulse laser generated by the laser diode with a pulse width of 160 ps and a low timing jitter singlephoton detector based on a multipixel photon counter with a timing jitter of 417 ps are used to reduce the overall timing jitter of the system. The ranging experiment results show that within the 2 -meter ranging range, the distance measurement accuracy of the singlephoton ranging system could reach 370
