Abstract

A triangulation scanner includes a projector, a camera, and a processor, the projector projecting a first pattern of light on a first point during first intervals and a no light during second intervals, the camera including an optical detector, a first accumulator, and a second accumulator, the optical detector receiving reflected light from the first point, the first and second accumulators summing signals from the optical detector during the first and second intervals, respectively, the processor determining 3D coordinates of the first point based at least in part on the first pattern, the summed signals from the first and second accumulators, and a speed of light in air.
