Abstract
A method for determining three-dimensional coordinates of an object point on a surface of an object, the method including steps of: providing a source, a projector, and a camera; in each of two instances: spatially modulating source light; sending a modulator pattern of light through the projector lens to form light spots; filtering the spots with a pinhole plate; propagating light from the light spots onto the object to produce a fringe pattern; imaging the object point with a camera lens onto an array point of the photosensitive array to obtain first and second electrical data values from the photosensitive array; and determining the three-dimensional coordinates of the first object point based at least in part on the first electrical data value, the second electrical data value, and a baseline length.
