The light collected by a camera consist of multiple components: The direct component of light that traveled directly from a surface in the scene to the camera and many multibounce components made up of light that has been reflected more than once within the scene. The direct component carries the information for a conventional image of the scene in the line of sight. The multibounce components contain additional information about scene appearance for all parts of the scene that the collected light has interacted with before detection.

Non-Line-of-Sight (NLOS) Imaging systems reconstruct images of scene using indirect light from reflections off a diffuse relay surface. After illuminating the relay surface with short pulses, the returning light is detected with high time resolution single photon cameras. We thereby capture video of the light propagation in the visible scene and reconstruct images of hidden parts of the scene.

This method has potential practical applications for imaging into caves, assessment of infrastructure like buildings from the air, scouting of caves for potential human habitation on moon and mars, collision avoidance, robot navigation and path planning, as well as disaster response, military reconnaissance , and law enforcement.

Over the past decade NLOS imaging has seen rapid progress and we can now capture and reconstruct hidden scenes in real time and with high image quality. In this presentation I will give an overview over the imaging technologies, reconstruction methods, and applications driving NLOS imaging and provide an outlook for future development.
