a.) The camera Is positioned on the side of the wall and Is looking down at the floor: It cannot see what Is behind the wall but Its field or view Is placed beyond the edge of the obstacle. b.) A side view shows that the target is hidden behind the wall. To see the hidden target around the corner, laser pulses are sent to the floor. c.) The light then scatters off the floor and propagates as a spherical wave behind the obstacle, reaching the hidden object. This light is then in turn scattered back Into the field of view of the camera. The SPAD camera records both spatial and temporal information on the propagating spherical light wave as it passes through the field of view, creating an elliptical pattern where it intercepts the floor. An example of the spatially resolved raw data, as recorded by the camera for a fixed time frame as the ellipse passes In the field of view. Is shown In the Inset.
