Two circular apertures are placed in the exit pupil of an imaging system as shown in Figure P5.1. Light from these two small openings create a fringe pattern in the image plane.

(a) Find the spatial frequency of this fringe in terms of the center-to-center spacings of the two openings, the wavelength \(A\), and the image distance \(z_{i}\).

(b) The openings are circular and have diameter \(d\). Specify the envelope of the fringe pattern caused by the finite openings in the pupil plane.
