| Summary: | Moire Interferometry is a whole field, high sensitive technique for deformation measurement. It is a good experimental technique that has a combination of high sensitivity, optical contrast, range and spatial resolution. This experimental technique relies on interference of high frequency deformable specimen grating with a fixed reference grating to obtain contours of in-plane displacement components with sub-micron sensitivity. In this project, a moire interferometric strain sensor is designed and developed to improve the shortcomings and limitations of the commercial available moire interferometer, which is unable to resolve very small and localized vicinity. |
