Laser speckle based digital optical methods in structural mechanics: A review

Laser Speckle Correlation, Electronic Speckle Pattern Interferometry and Digital Holographic interferometry have evolved for decades to become relevant techniques in many fields of today’s wide spectrum of knowledge and disciplines. Indeed, with today׳s advances in optics, photonics, electronics and computing there are many important applications for them and strictly speaking there are an almost infinite number of applications that one can...
