Abstract
Two novel optical configurations for obtaining the slope change contou ring of a three-dimensional object are presented. The slope change inf ormation is coded in the phase of the interference fringes by a slight rotation of the specimen surface. The methods offer controllable sens itivity capabilities. The methods are theoretically described and the limitative aspects are briefly discussed. The proposals are supported by experimental evidence.
