Abstract EN
The fringe projection technique has been widely used in optical measurements.
In this paper, we demonstrate a scheme to measure the 3D displacement of a deformed sample using Talbot fringe projection.
In this process, we designed a two-dimensional square Talbot hologram.
In this approach, we used the basic principle of triangulation, and a computer-controlled liquid crystal spatial light modulator (LC-SLM) was placed in the optical path.
The Talbot array hologram was displayed on the LC-SLM screen and projected onto the surface of a sample.
Two patterns were recorded: one before and one after deformation.
We simultaneously acquired the in-plane and out-of-plane displacements using the digital image correlation (DIC) method.
This scheme is simple and easily implemented.
Theoretical and experimental results are presented.
