Sawtooth profile fringes with a two-grating interferometer.
The theory of fringe formation of arbitrary profile in a two-grating interferometer is developed emphasizing sawtooth profile fringes. Two methods of fringe synthesis are given: the spatially incoherent illumination method, leading to a coherent synthesis and the temporally incoherent (polychromatic) illumination method, leading to an incoherent synthesis.
