Abstract

Talbot effect and interferometrical fringes phenomena combined with computer-generated moire are employed in order to enhance the detection of the displacements of one surface. The high sensitivity achieved, easily assembly and the possibility to change automatically the reference pattern tourn competitive such methods as compared to other but complex. The range of application for each case is estimated.
