N2 - In this work we present results of measuring deformations on cylindrical objects. The proposed technique is based on panoramic vision principles with convex mirrors, particularly paraboloid mirrors. ESPI techniques are then combined with this panoramic vision system to create a technique suitable of being applied on cylindrical objects. Some results obtained with first-approach mirrors are shown. The system is composed of two modules, illumination and capture, each one needs a paraboloid mirror. Nevertheless this is not the only possible setup when using convex mirrors, an alternative setup is also proposed but is not studied experimentally. Results show the feasibility of the system to determine full-field deformations inside a cylindrical object. The systems is currently being patented and points to an attractive solution in cylindrical or panoramic geometries.
