Abstract
A spatial phase sensor having a lens or opening, or the like, through which electromagnetic radiation signals are directed. Mechanism is provided for receiving the electromagnetic radiation signals and for providing an enhanced electrical signal therefrom. The spatial phase of the electromagnetic radiation signals is first determined by analysis of the polarization vectors of the electromagnetic radiation signals and a sensor is provided for converting the electromagnetic radiation signals into electrical signals containing data corresponding to the determined spatial phase of the electromagnetic signals.
