Non-Line-of-Sight (NLOS) imaging can be used to detect and image hidden objects around the corner, behind smoke and so on. It is of important value to many research fields like machine vision, public security, medical imaging, disaster relief and autonomous vehicles. This technology utilizes a pulsed laser and a time-resolved detector to scan and detect a certain surface. At present, NLOS imaging still has some shortcomings such as time-consuming in scanning and computer-reconstruction. To overcome these shortcomings, a rapid staring detection and reconstruction method is proposed. The simulation results show that it can be used to detect highly-scattered objects and widen the field of view effectively.
