Abstract

A portable phase shifting shearing TV-holography apparatus for non-destructive testing is presented in this paper. This apparatus has been utilized in the inspection of large area aluminum coated honeycomb structure of aeronautical composite for off-stick defect testing. The working principle and the configuration of the system are described. The structure will be detailed. Satisfactory result have been obtained with this system. Wrapped defect phase pattern will be shown.
