    Simultaneous Measurement of Three-Dimensional Displacement Gradients Using Tri-Color Michelson-Type Digital Shearography: Comparison and Optimization of Optical Setups

    Simultaneous Measurement of Three-Dimensional Displacement Gradients Using Tri-Color Michelson-Type Digital Shearography: Comparison and Optimization of Optical Setups


    In recent years, spatial phase-shift technique has been applied in digital shearography to obtain interference phases, solving the problem that temporal phase-shift technique cannot be used in dynamic measurement. In this article, two optical setups of spatial phase-shift digital shearography are compared. The issue of optical setup parameter optimization is also discussed.
