Abstract

We describe an optical setup based in the Talbot effect, which uses two mutually incoherent sets of self-images to display simultaneously interferometric bright-field and dark-field images, in almost any combination of two complementary view-fields. This feature allows us to sample the object under test in many different places. A spatial filter can be used, to visualize the interferametric fields with uniform irradiance; as gray variations. Several experimental results that verify our technique are shown.
