Spectrum Compression of a Short Pulse from a Central Obstructed Circular Aperture in the Far-field
The spectrum changes of a Gaussian pulse in the far-field is studied with Fresnel diffraction integral when it is incident on a circular aperture with a central obstruction. It can be shown that the central obstruction will cause diffracted spectrum compressed, compared with that of the normal circular aperture without a central obstruction. This novel effect could be useful for optical engineering or optical communications.
