The efficiency of a Lyot stop in reducing diffraction effects in a simple optical system is analyzed. The transformation rules of Fourier optics are used to follow the optical signal through the system. This analysis reduces the problem to the evaluation of a two-dimensional integral. An approximate analytic technique for evaluating this integral is presented. The final result is a simple formula for calculating the diffraction-reduction efficiency of the Lyot stop. A comparison of this work with other published work is also presented.
