Paper Abstract

The Ronchi test is a well-known method for the testing of optical components and systems, and can be studied by ray tracing and lateral shearing interferometry. In this paper, the Ronchi test is applied using an LCD, for generating gratings with different periods for the dark and light zones, in order to obtain sharpening of the fringes. Experimental and computer simulations will be presented for parabolic surfaces.
