It uses a high-order areal quadrature over the aperture, then exploits a single 2D nonuniform fast Fourier transform (NUFFT) to evaluate rapidly at target points (of order 10^7 such points per second,  ...  We present a fast algorithm for computing the diffracted field from arbitrary binary (sharp-edged) planar apertures and occulters in the scalar Fresnel approximation, for up to moderately high Fresnel  ...  Acknowledgments This work benefited from discussions with David Spergel, Robert Vanderbei, Stuart Shaklan, and Eric Cady.
