Non-line-of-sight imaging is typically limited by loss of directional information due to diffuse reflections scattering light in all directions. Here, the authors see around corners by using vertical edges and temporal response to pulsed light to obt

Compressive sensing has been used to demonstrate scene reconstruction and source localization in a wide variety of devices. To date, optical compressive sensors have not been able to achieve significant volume reduction relative to conventional optic

Non-line-of-sight (NLOS) imaging is a rapidly growing field seeking to form images of objects outside the field of view, with potential applications in autonomous navigation, reconnaissance, and even medical imaging. The critical challenge of NLOS im

Detector and electronics dead times distort photon detection histograms at high flux, but can be mitigated by probabilistic modeling identifying the sequence of detections as a Markov chain.

Imaging and Applied Optics 2019 (COSI, IS, MATH, pcAOP).
Accurate modeling of high-flux single-photon counting systems requires accounting for the dependence of photon detection times. The limiting distribution of the resulting Markov chain can be used for lidar depth estimation and histogram correction.

In time-correlated single-photon counting (TCSPC), photons that arrive during the detector and timing electronics dead times are missed, causing distortion of the detection time distribution. Conventional wisdom holds that TCSPC should be performed w

Single-photon lidar (SPL) is a promising technology for depth measurement at long range or from weak reflectors because of the sensitivity to extremely low light levels. However, constraints on the timing resolution of existing arrays of single-photo

Recent advances in silicon photonics have enabled large-scale optical phased arrays for applications such as beam steering and directional light detection. However, to date, these results have only been applied to coherent light. Many applications, i
Subtractive dither is a powerful method for removing the signal dependence of quantization noise for coarsely-quantized signals. However, estimation from dithered measurements often naively applies the sample mean or midrange, even when the total noi

Using detector arrays can speed up lidar systems by parallelizing acquisition. However, current SPAD arrays have time bins longer than typical laser pulse durations, resulting in measurement errors dominated by quantization. We propose an optical tim
