Secure interferometric communications in free space
Abstract
N-slit interferometry is applied to generate a series of optical signals to represent given alphabetical characters. These interferometric characters are propagated through free space and recorded by a digital detector. The unique and specific interferometric representation of alphabetical characters is also generated theoretically. Attempts to intercept optically the signals lead to distortions of the predetermined interference.
