The noise power spectrum was calculated for groove wall undulation based on the Fraunhofer diffraction theory. Groove profile fluctuations were modeled as fluctuations in the groove profile parameters. Changes in the diffracted light field were assumed to vary linearly with the changes in the groove profile. The expression for the noise power spectrum was obtained by statistical averaging, and the contribution of the undulation to the noise power spectrum was found to depend on the depth of the undulating area.
