A Single Photon Counting Ranging System Tolerating 100Klux Background light

In this paper, a single photon ranging system is proposed and designed. The depth data processing and acquisition are completed on the SOC chip, and 60 × 1 dynamically adjustable SPAD array pixels are integrated. The histogram distribution of photon arrival time is realized based on TCSPC. The histogram algorithm is implemented in MCU firmware, which can resist outdoor strong light, the system is shown to work up to 100 Klux of background light with depth error lower than 15 mm at 1000 mm.
