AI Technical Summary
Existing single-photon ranging technology lacks accuracy and is susceptible to errors in analog pulse intensity and time interval measurement, resulting in inaccurate distance measurements.
A hybrid distance measurement system combining full waveform and single-photon counting is adopted. The output signal of the single-photon detector is acquired by a high-speed ADC, and first-order local extremum point analysis and waveform fitting are performed to identify and crop the peak time of the single-photon signal. Combined with the time-correlated single-photon coincidence counting method, the measurement accuracy is improved.
It effectively suppressed distance walking error and time interval measurement error, and improved the accuracy of single-photon ranging.
