| Generalized N-Slit Interferometric Calculations |
|---|
Numerical calculations, near or far field, for the interference produced by the interaction of laser light with an array of N-slits. Input paramenters include: wavelength, slit dimensions, number of slits, distance from the slit array, or grating, to the interference plane. Graphical output includes the central and secondary diffraction orders.
Note: the interferometric calculations mentioned here are performed using equations derived from the application of Dirac's notation to propagation in a given geometry. The principles of this approach are described in F. J. Duarte, Tunable Laser Optics (Elsevier-Academic, New York, 2003) (see Chapter 2). This particular interferogram was first published in F. J. Duarte, On a generalized interference equation and interferometric measurements, Opt. Commun. 103, 8-14 (1993).
