A practical optical sensor for rough surface diagnostics has been developed for applications in mechanical engineering. The principle of the sensor is based on digital speckle correlation. First, the measuring principle and the optical system arrangement are described, then optical measurements on different rough surfaces are compared with mechanical stylus measurements and the results are discussed with consideration of the advantages and differences of the two methods.
