Abstract

High-speed measurement of temporally varying displacement derivatives of a deformed object is an important and challenging problem in precision metrology. This paper proposes an approach for temporal deformation analysis using digital holographic interferometry, where a series of digital holograms is recorded corresponding to a test object subjected to variable load. Numerical reconstruction followed by superposition of these holograms provides a huge stack of interference or fringe pattern data, which needs to be processed to extract the displacement derivative information. This operation involves great computational complexity, and we propose a highly efficient Wigner–Ville distribution method based on a graphics processing unit to address the challenge. Experimental results clearly demonstrate the viability of the proposed approach for high-speed deformation analysis in digital holographic interferometry.
