The package enables the user to draw (using PSTricks) the
diffraction patterns for different geometric forms of apertures
for monochromatic light (using PSTricks). The aperture stops
can have rectangular, circular or triangular openings. The view
of the diffraction may be planar, or three-dimensional. Options
available are the dimensions of the aperture under
consideration and of the particular optical setting, e.g. the
radius in case of an circular opening. Moreover one can choose
the wavelength of the light (the associated color will be
calculated by the package).
