26. As we have employed it here, the Gaussian transmission function in Eq. (2) is chosen for theoretical convenience, although for electronic optics it is physically appropriate as well. In the results it will not make any qualitative difference; in fact, in deriving the form in Eq. (15) we further approximate the actual case using a simple rect function as the impulse response of the lens.
27. In this simplification, the assumption is that the phase terms in the integrand of Eq. (3) involving the variables x’, y’ do not vary appreciably within the interval wr. For a consideration of the extent of this type of phase variation, the reader is referred to D. A. Tichenor and J. W. Goodman, J. Opt. Soc. Am. 62, 293 (1972).
