Paper Abstract

Two-dimensional diffraction calculations for image forming systems and laser systems require a computer which is fast and has a reasonably large amount of memory. We have written a program, IMAGE, for the IBM-PC to perform diffraction calculations. It represents the complex electric field with a 128 by 128 array. IMAGE is written in C with an FFT routine written in assembly language. It produces numerical and graphical output for user described optical systems. Input parameters include F# or pupil diameter, wavelength, aberration coefficients and Gaussian amplitude scale factor. Output includes geometric spot diagram, encircled energy, point spread function, wavefront contours, MTF, and PTF.
