Abstract

Liquid Crystal on Silicon (LCoS) displays can be very useful in numerous optical applications due to some technical features of these devices, like the large fill factor and resolution. Here, we have developed a study related to the performance of the LCoS displays. It has been demonstrated that the LCoS display produces certain amount of depolarized light and the Mueller-Stokes formalism has been required for a full polarimetric characterization. In a previous paper we obtained the experimental Mueller matrix of the LCoS display as a function of the addressed gray level, at the very small angle of 2 degrees between the incident beam and the LCoS display normal, and for the wavelength of 633 nm. In the present paper we extend this study to different angles of incidence in order to analyze the influence of this parameter on the performance of the LCoS display. We also analyze the influence of the angle of incidence on the degree of polarization of the reflected beam. A comparison between the obtained results is presented in this paper.
