Paper Abstract

A shearing system for crack inspection on tanks is reported. A compact device comprised of a Michelson type shearing interferometer, a diode laser, a phase shifting element, a pzt to deform the object under test and a car with magnetic wheels to move the full system. It is proved that a light car with magnetic wheels can support vertically a shearing system and obtain in real-time wrapped deformation phase without decorrelating the fields. This phase deformation system would enable us to analyze big tanks with confidence and security.
