Abstract

This paper presents an overview about some possibilities to use electronic speckle pattern interferometry for measuring in cylindrical or in-plane polar coordinates. Out-of-plane deformation measurement of cylindrical surfaces can be done for either internal or external cylinders using conical mirrors. A special configuration for measuring long internal cylinders is also discussed and a practical application is presented. Another configuration uses conical mirror for double illuminate a flat area to measure the in-plane radial displacement component. This configuration has been successfully used for 2D translations, stress and residual stresses measurements.
