Abstract
A triangulation scanner system and method of operation is provided. The system includes a projector that projects a first pattern of light at a first light level during first time intervals and project the first pattern of light at a second light level during second time intervals, the second light level being different than the first light level. A first camera has a first photosensitive array, the first photosensitive array having a first pixel with an optical detector, a first memory, and a second memory. The first memory storing a first stored signal from the optical detector during the first time intervals, the second memory storing a second signal from the optical detector during the second time intervals. A processor determines three-dimensional coordinates of the first point based at least in part on the projected first pattern of light, the first stored signal, and the second stored signal.
