title: Talbot interferometer with simultaneous dark and bright fields.
abstract: We describe an optical setup for implementing a Talbot interferometer that uses two mutually incoherent sets of self-images to simultaneously produce interference bands due to dark and bright fields. A spatial filter can be used to visualize these fields without interference fringes. Experimental results are included.
