Build Confocal NLOS Imaging platform

according to O’Toole et al.

Confocal NLOS imaging Setup

In mid-2018, under the guidance of our mentor, we plan to follow the work of Stanford University O’Toole and others on time-resolved NLOS imaging

M. O’Toole, D. B. Lindell, and G. Wetzstein, “Confocal non-line-of-sight imaging based on the light-cone transform,” Nature, vol. 555, no. 7696, p. 338, 2018, doi: https://doi.org/10.1038/nature25489.

We purchased corresponding equipment, including ultrafast pulse lasers, single-photon avalanche diodes, time-dependent single-photon counters, etc., and purchased an optical platform.

Although our laboratory does not have a basis for optical experiments, we have established a confocal NLOS imaging system. This system can currently image some simple NLOS scenes, but there is still a problem of large time jitter (which means a low horizontal resolution). At present, we are trying our best to improve the reconstruction quality from both perspective of hardware and algorithm.
