Abstract
An improved system and method of decoding a phase modulated encoding of a pair of optical beams is preferably achieved by generating a plurality of optical fringes from the pair of optical beams, sampling each optical fringe and generating a set of at least three phase offset signals from each sampled optical fringe, each generated signal having a unique and known phase difference relative to each sampled optical fringe, and by deriving a quantitative representation of the phase encoding of the pair optical beams from information provided from each set of generated signals. Optionally, the quantitative representation is converted into an electric signal.
