Comparison of deterministic phase coding with random phase coding in terms of dynamic range.

Phase coding techniques are useful for lowering the dynamic range of the recorded spectrum in digitally generated hologram and kinoform memories. Two types of phase coding schemes, random phase coding and deterministic phase coding, which is independent of the input sequence, are compared in terms of the dynamic range of the spectrum. A probabilistic analysis shows that deterministic phase coding is advantageous over random phase coding. It is shown that Frank codes and a specialized form of Schroeder codes are effective for deterministic phase coding.
