Abstract

Holographic interferometry and laser speckle techniques make it possible to measure deformation and vibration of diffusely reflecting surfaces with sensitivities related to laser wavelengths. The relationship between these methods are discussed with views to formation of interference fringes observed and their recent advances for quantitative and automatic measurements.
