Claim:
1. A laser metrology system comprising: a measurement beam, wherein said measurement beam is modulated; a beam splitter for splitting said measurement beam into a local oscillator beam and a transmitted beam; an optical assembly for expanding and projecting said transmitted beam to cover a measured area on a surface of a target structure and for receiving and focusing a plurality of reflected beams, said plurality of reflected beams being a return of a single projection of said transmitted beam from a plurality of measured points on said surface of said target structure within said measured area; a beam combiner for combining said plurality of reflected beams and said local oscillator beam into a detection beam; a detector for processing said detection beam, said detector comprising: a range processor in communication with said detector electronics, wherein said range processor computes dimensional data for said plurality of measured points within said measured area from said informational data based on said single projection of said transmitted beam on and reflection of said plurality of reflected beams from said measured area on said surface of said target structure, calculates a range value for said each one of said plurality of measured points, and reports said range value for said each one of said plurality of measured points to a controller for display, and wherein a plurality of range values for said plurality of measured points are shown as a two-dimensional representation of said target structure.
