Abstract:
1. A 3D imaging system, comprising: first and second rolling shutter photosurfaces comprising pixels; a first shutter operable to gate on and off the first rolling shutter photosurface; a light source controllable to transmit a train of infrared light pulses to illuminate a scene; a controller that controls the first shutter to gate the first rolling shutter photosurface on and off responsive to transmission times of the light pulses and opens and closes bands of pixels in the first and second rolling shutter photosurfaces to register reflected light, the reflected light is reflected from the light pulses by the scene; and a processor that determines distances to the scene responsive to amounts of light registered by pixels in the first and second rolling shutter photosurfaces, wherein the first and second rolling shutter photosurfaces comprise respective arrays of pixels, the first rolling shutter registers substantially only infrared light from the scene, and the second rolling shutter photosurface registers infrared and RGB light from the scene.
