低成本亚毫米精度单光子测距技术

Abstract

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
