[ What is claimed is:] [1.] A method for measuring range to each of multiple locations on a surface comprising the steps of:projecting a plurality of zones of light onto said surface at each of said multiple locations,simultaneously imaging said zones onto a photodetector array, the axis of said imaging spaced angularly from each said projection,analyzing the output of said array, and,from said analysis, determining the range to each of said locations on said surface.
