Single-Photon Reflectivity and Depth Imaging by Continuous Measurement of Arrival Time of Photons

Abstract: We demonstrate a reflectivity and depth imaging Lidar system based on a novel photon arrival time measurement method. In this method, the arrival time of photons in a scanning position is continuously measured with a common starting point. The number of laser pulses is counted by a specially designed field programmable gate array (FPGA) control module as the coarse time of arrival photon. Time interval between arrival photon and the nearest coming laser pulse is measured by a time-correlated single-photon coun… Show more

“…Eqs. 7and (8) show the intensities detected by the dual Gm-APDs based on polarization transmission theory. Each measurement only depends on one of the two "attenuation factors", G1 and G2, and thus each of them can be retrieved uniquely and the paths can be separated.…”

“…Besides the interest in fundamental science and research, vortex beams [26][27][28] have a number of applications. For example, in near-field optical communication, each OAM mode carrying an independent data stream can be multiplexed and demultiplexed efficiently, providing a higher transmission capacity and spectral efficiency [29].…”

“…Using the time-correlated single-photon counting (TCSPC) technique, high temporal resolution of picosecond can be achieved. Therefore, the TCSPC lidar has great application prospect in the fields of remote sensing [1,2], spacecraft landing [3,4] and environmental monitoring [5,6], as well as low-light level imaging [7][8][9]. Particularly, with the development of single-photon avalanche diode (SPAD) array devices with independent timing capabilities for each pixel, the array-based TCSPC lidar has become a research hotspot in recent years [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”
