RICKENSTORFF, C.; FLORES, E.; OLVERA-SANTAMARIA, M.A.  e  OSTROVSKY, A.S.. Modulation of coherence and polarization using nematic 90°-twist liquid-crystal spatial light modulators. Rev. mex. fis. [online]. 2012, vol.58, n.3, pp.270-273. ISSN 0035-001X.

A technique for modulating the coherence and polarization of the electromagnetic field using 90°-twist liquid-crystal spatial light modulators (LC-SLMs) is proposed. The controlled change of the statistical properties of light is achieved through computer generated random signals applied to a pair of 90°-twist LC-SLMs arranged in an interferometric setup. Experimental results obtained using Holoeye LC2002 modulators show the efficiency of the proposed technique.
