Abstract
A holographic method for surface mapping is described, and the results obtained, with respect to accuracy and data retrieval rate, are compared to those obtained by stereophotograrnmetry. With the holographic technique, in which a real image of the surface is scanned automatically, greater accuracy is achieved and data are retrieved more rapidly. A high-power pulsed laser technique is also described which allows extending the method to non-stationary objects. Although developed primarily for automotive model mapping, the method is applicable to other areas such as anthropometry.
