We present a novel technique for measuring phase modulation in a liquid crystal television (LCTV) panel using the fractional-Talbot effect. We show that the phase modulation property in an LCTV can be obtained by measuring the contrast ratio of the Fresnel diffraction field at one quarter of the Talbot distance. We also generate a multilevel phase grating that produces a Talbot array illuminator to verify the experimental measurement result.
