title: Infinite fringe moire deflectometry.
abstract: Phase object analysis is discussed and demonstrated using infinite moire deflectometry in which the grooves of the two Ronchi rulings are parallel. It is shown that this mode of operation may be advantageous in some cases such as automatic picture processing. In addition, the interpretation of the deflectometry is more straightforward.
