<p>An improved system and method of decoding a phase modulated encoding of a pair of optical beams (112a, 112b) is preferably achieved by generating a plurality of optical fringes (112a, 112b) from the pair of optical beams, sampling each optical fringe and generating a set of at least three phase offset signals (142a, 142b, 142c) 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 (112a, 112b) from information provided from each set of generated signals (142a, 142b, 142c). Optionally, the quantitative representation is converted into an electric signal (162).</p> |
