Non-line-of-sight imaging using a time-gated single photon avalanche diode

Year: 2015

Type: article

Abstract: By using time-of-flight information encoded in multiply scattered light, it is possible to reconstruct images of objects hidden from the camera's direct line of sight. Here, we present a non-line-of-sight imaging system that uses a single-pixel, single-photon avalanche diode (SPAD) to collect time-of-flight information. Compared to earlier systems, this modification provides significant improvements in terms of power requirements, form factor, cost, and reconstruction time, while maintaining a comparable time resolution. The potential for further size and cost reduction of this technology make this system a good base for developing a practical system that can be used in real world applications.
