Abstract

We describe the interference fringes produced when periodic and aperiodic (random) amplitude masks are illuminated with partially coherent light. Periodic transmission gratings and the recordings of laser speckle patterns have been used to constitute the masks. We will discuss applications to measure the motion of objects and in particular study the rotational motion measurement using random masks.
