A Simplification of Lee's Method of Generating Holograms by Computer.

摘要: This letter points out a simplification in a recently published method for producing computer-generated holograms. 1 When this simplification is used, the required memory size as well as plotter resolution are reduced. The possibility of such a sim plification was suggested2 during a discussion of Lee's original presentation at the 1968 OSA meeting in Washington. A simi larity was noted between Lee's method and work presented at the same meeting and published in Ref. 3. Lee decomposes a complex-valued function F (u, v) into four real and …
