title: Retroreflective grating generation and analysis for surface measurement.
abstract: An efficient system for retroreflective grating generation andanalysis has been constructed to measure the derivative and the contourof specular surfaces. In this system, a new optical configurationhas been provided to generate and capture a grating image with aretroreflective screen. Tests show that the system can detectindents and outdents with a maximum depth of less than 10mum. The method can be developed for automated industrialinspection and machine vision.
