A Single-Shot Non-Line-of-Sight Range-Finder

A Single-Shot Non-Line-of-Sight Range-Finder

The ability to locate a target around a corner is crucial in situations where it is impractical or unsafe to physically move around the obstruction. However, current techniques are limited to long acquisition times as they rely on single-photon counting for precise arrival time measurements. Here, w...

However, current techniques are limited to long acquisition times as they rely on single-photon counting for precise arrival time measurements. Here, we demonstrate a single-shot non-line-of-sight range-finding method operating at 10 Hz and capable of detecting a moving human target up to distances of 3 m around a corner. Due to the potential data acquisition speeds, this technique will find applications in search and rescue and autonomous vehicles.https://www.mdpi.com/1424-8220/19/21/4820lidarnon-line-of-sighttime-of-flight
