A method for determining three-dimensional coordinates of an object point on a surface of an object, the method including steps of: sending a beam of light to a diffraction grating; sending a first diffracted beam and a second diffracted beam to an objective lens to form at least two spots of light, which are passed through transparent regions of a plate to produce a first fringe pattern on the surface of the object; imaging the object point illuminated by the first fringe pattern onto a photosensitive array to obtain a first electrical data value; moving the plate to a second position; sending spots through plate to produce a second fringe pattern on the surface of the object; imaging the point onto the array point to obtain a second electrical data value; and calculating the three-dimensional coordinates of the first object point.
