Abstract: A structured light 3D scanner consisting of a specially designed fixed pattern projector and a camera with a specially designed image sensor is disclosed. A fixed pattern projector has a single fixed pattern mask of sine-like modulated transparency and three infrared LEDs behind the pattern mask; switching between the LEDs shifts the projected patterns. An image sensor has pixels sensitive in the visual band, for acquisition of conventional image and the pixels sensitive in the infrared band, for the depth acquisition.
