Paper Abstract

A tilt-angle-measurement system for liquid crystal cells has been implemented by using the phase retardation extrema method. It includes the rotation of the liquid-crystal film in a linearly polarized monochromatic light and the measurement of the transmitted intensities as a function of the incident angle with photodetectors. The average tilt angle is determined. The performance of this prototype system has been assessed both by numerical calculation and reliability measurement.
