In order to do this analysis we compute the reconstruction of Fresnel holograms at several distances using the different parts of the complex distribution (real and imaginary parts, amplitude and phase) as well as using the full complex information adjusted with a method that combines two configurations of the devices in an adding architecture. The RMS error between the amplitude of these reconstructions and the original amplitude is used to evaluate the quality of the information displayed. The results of the error analysis show different behavior for the reconstructions using the different parts of the complex distribution and using the combined method of two devices. Better reconstructions are obtained when using two devices whose configurations densely cover the complex plane when they are added. Simulated and experimental results are also presented.9 p.application/pdfeng(c) Society of Photo-Optical Instrumentation Engineers (SPIE), 2003HolografiaPantalles de cristall líquidProcessament òptic de dadesHolographyLiquid crystal displaysOptical data processinginfo:eu-repo/semantics/article5137552014-02-07info:eu-repo/semantics/openAccess
