This paper reports on a newly developed algorithm for improving the previously reported basic theory of computer-generated polarization holography. An application of the algorithm to the basic theory shortens the hologram making time, which uses a limited quantity energy of an illuminating uv spot light. A relation between a polarization angle of the illuminating uv beam and an effective amplitude transmittance Tp of a crystal-analyzer pair is derived. Furthermore, a method for correcting an effect of the pre-existing unbalance of the degree of the density balance of M-centers in a binary state is proposed. Also, the theory of the method is theoretically discussed in detail together with a derivation of the θ vs Tp curves characteristic of this case.
