Paper Abstract

The paper presents the analysis of the strain distribution of turbines blades. The holographic moiré technique is used in conjunction with computer analysis of the fringes. The application of computer fringe analysis techniques reduces the number of holograms to be recorded to two. Stroboscopic illumination is used to record the patterns. Strains and stresses are computed.
