A novel, to our knowledge, configuration for the design and
fabrication of zero-order computer-generated holograms in which each
pixel is split into two centrosymmetric equal-sized regions is proposed
and tested. In a manner similar to other approaches this
configuration also permits the encoding and the reconstruction of a
complex function that exhibits phase as well as amplitude variations by
use of a phase-only filter. A detailed mathematical analysis is
followed by evaluation of the error of the encoding approach, which is
calculated and compared with the error exhibited by other
approaches. Computer simulations as well as optical experiments
demonstrate the capabilities of this novel configuration.
