Paper Abstract

We present a study of the intensity variations of the joint Fourier spectrum when one of two input objects is rotated while the other remains fixed by determining the average contrast as a function of the angle of rotation. The visibility behavior is explained in a theoretical and experimental way for simple test objects whose fine analog rotations are acquired with an optomechanical system that uses a high precision rotatory stage.
