Paper Abstract

Currently, high spatial density/high resolution data bases of the deformation of structures are available using Computer Aided Holometry (CAH) for (1) static deformation, (2) periodic motion and (3) dynamic deformation at widely separated instances of time. However, many practical structures are nonlinear and there exists a need to measure how a surface moves as a function of time. This paper presents a high frame rate, shifted phase video holographic method for measuring surface motion as a function of time. The theory, hardware, simulation results and limitations are discussed.
