실험 목적 This lab aims to discover a method based on diffuse light: Speckle interferometry.
The Kit allows also study the method of treatment of the interference fringes to obtain quantitative information on the optical phase: the phase shift method.
The experiment aims to learn the user to conduct optical phase unwrapping.
