|Abstract:||Motivated by the Talbot-effect, a grating projection system was designed. Periodic patterns were produced from the projection of a grating illuminated by collimated laser beam. The self- image of the grating is projected on object surface and the deformed grating image is captured by a CCD Camera for subsequent analysis. The phase variation is achieved by using a linear translation stage incorporated to the grating. In this application, a coin with an uneven surface of less than 0.2 mm is tested to demonstrate the validity of the method. The experimental results are compared with test results using mechanical stylus method.|
