This paper gives a general review of the production of high temperature gratings and their application to deformation measurement. The fabrication techniques for gratings and deformation measurement methods using the gratings are discussed. The review is confined to in-plane moire and moire interferometry methods. Some typical applications in high temperature deformation measurement are briefly discussed.

High Temperature Gratings for the Moiré and Moiré Interferometry Methods and their Application to Deformation Measurement - A Review

In this study, a new experimental method for measuring the creep of pipeline using moire interferometry was proposed Curved-surface-deformed grating replicating technique was combined with the high-temperature-resistant grating and moire interferometry method, and was applied to measure the creep of a 475°C main steam pipeline in the Qinghe Power Plant for 3600 h The measuring principle and experimental techniques are described The measuring error and experimental results are discussed in detail

The Creep Measurement of 475°C Pipeline Using Moire Interferometry

Experimental study on the damage progression of an aluminium plate irradiated by CO2 laser

In this paper, a grid method was used to measure the residual deformation ofa loaded aluminium plate irradiated by CO 2 Laser. The residual strain fields near the illuminated area at different irradiation times were obtained. The experimental results were discussed in detail.
