1 January 1993 Micro phase-shifting interferometer for surface measurement
Author Affiliations +
Design and application of a rigid miniaturized phase shift interferometer is presented. The matchbox size instrument has a Twyman-Green setup and an integrated CCD camera. A standard HeNe laser supplies the light through a monomode fiber. The advantages in measuring big and small objects are discussed. The sensor-like instrument can even be integrated into manufacturing equipment.
