**5. Conclusions**

This Chapter provides a study of LCoS displays for their application in the generation of digital holograms. In particular, the analysis presented in this Chapter can be used as a guideline to maximize the efficiency of LCoS display in digital holographic applications.

In particular, this Chapter provides a characterization and optimization method, based on a combination of the Mueller formalism and the Jones formalism, suitable to maximize the efficiency of the addressed holograms. Besides, experimental evidence is provided for the time-fluctuations of the phase phenomenon, which degrades the performance of LCoS displays. In this way, a discussion of the damaging effect of such phenomenon, when generating digital holograms, is included. Finally, we experimentally prove that, to maximize the efficiency of digital holograms generated with LCoS displays in presence of phase fluctuations, is important to find a trade-off between phase modulation depth and amplitude of the time-fluctuations. To this aim, different mapping schemes for phase-only distribution implementation are reviewed.
