In the mastering process of optical discs, information is transferred to the master disc surface and stored in the form of a sequence of pits. For analysis and control of the disc manufacturing process, the dimensions of such pits are assessed with optical diffraction measurements. The results of such measurements can be interpreted in a relatively simple manner by using scalar diffraction theory.
