Abstract

Optical techniques are now broadly used in the field of experimental mechanics The main advantages are they are non intrusive and no contact Moreover optical techniques lead to full spatial resolution displacement maps enabling the computing of mechanical value also in high spatial resolution For mesoscopic measurements digital image correlation can be used Digital holographic interferometry is well suited for quantitative measurement of very small displacement maps on the microscopic scale This paper presents a detailed analysis so as to compare digital Fresnel holography and digital imageplane holography The analysis is based on both theoretical and experimental analysis Particularly a theoretical analysis of the influence of the aperture and lens in the case of imageplane holography is proposed Optimal filtering and image recovering conditions are thus established Experimental results show the appropriateness of the theoretical analysis
