Paper Abstract

A Low Birefringence Polariscope (LBP) is developed to provide high-resolution, full-field thickness measurement of the liquid crystal cell. By rotating the analyzer, phase shift images can be captured and analyzed to obtain the gap thickness and uniformity of the liquid crystal cells. A comparative study with the commercial system shows good agreement. The proposed method yields accurate and repeatable full-field measurement of the LC cell with a simple experimental setup.
