An exact easy-to-compute formula has been derived for the transmitted amplitude of a Fabry-Perot interferometer for various surface irregularities. Some results for various surface defects obtained with this have been compared with the results of a Monte Carlo calculation which simply calculates the transmitted intensity as an incoherent sum from a distribution of elemental interferometers. Out of three possible defect distributions, namely, a random distribution of surface defects, a small curvature, and a small inclination, the random distribution is found to affect the line shape in a more severe way.
