Characterization of Reflective TN-LCD, Tuned in Phase-Only Modulation and to Six Wavelengths

Jorge Enrique Rueda, Ana Ludia Romero, Luis Alfonso Guerra


We present the results of the characterization of a liquid crystal spatial modulator LCR2500. The phase modulation ratio versus applied voltage and six wavelengths was determined. The basic experimental arrangement is a Mach-Zehnder interferometer, where one mirror is a LCR2500. We found the modulation exceeding 2pi radians. The method eliminates errors in the phase due to a mechanical noise.
