A new coding method for a CGH with pure phase based on the decomposition of any complex vector into two symmetrically situated conponent vectors with equal amplitude is proposed. In this method only two cells are needed for each sampling point as compared with the conventional types with three or four cells of Burckhardt's and Lee's configurations. Theoretical analysis of this proposal is given and some preliminary experimental results are presented.
