Optical Techniques for Deformation, Structure and Shape Evaluation :: Special Issue

About This Special Issue

There has been a growing demand for non-destructive quantitate evaluations with the development of materials science and integration technology. Optical technology shows its unique superiority in performance evaluations of materials and structures owing to the non-contact characteristic. This special issue welcomes research and review papers related to optical techniques and apparatus for non-destructive evaluations of deformation, structure and shape. We are particularly interested in new optical methods, developed optical instruments, typical applications in the fields of materials science, aerospace, electronics, biology, medical science, oceanography and other industrial areas.

Expected topics include, but not limited to:

1) Optical methods and apparatus, such as laser interference, moiré methods, the digital image correlation method, electronic speckle pattern interferometry, the grid method, geometric phase analysis, holographic interferometry, holo-photoelasticity, etc.

2) Fabrication techniques deformation carriers, including regular patterns (grating, grid) and random patterns (speckle) at different scales

3) Measurement accuracy improvement techniques, such as phase shifting, image processing, using ultraviolet light or X-ray, etc.

4) Measurement in unconventional environments, such as micro/nano scales, high temperature, dynamic state, vibration, curved surface, three dimensions, etc.

5) Applications in deformation measurement, mechanical properties evaluation, structure characterization, shape measurement, defect detection, surface flatness assessment, interfacial bonding strength estimation of various materials and structures.
