Paper Abstract

In order to accommodate to the available pixel numbers of spatial light modulators and to achieve the maximum possible storage capacity of a phase-code multiplexed holographic memory, it is often required to generate orthogonal phase- codes whose length (or order) is not a power of 2. This paper reviews various methods for the construction of Hadamard matrices of order n equals 4 m (with m a positive integer). It is meant to be tutorial in nature and useful in scope. No attempt is made to be exhaustive in the mathematic treatment. A complete list of Hadamard matrices for all orders n equals 4 m < 400 is given. The list can certainly be extended to even higher orders.
