Measurement of the phase modulation of liquid-crystal televisions by a noninterferometric technique

摘要

A simple method of measuring the phase-modulation properties of liquid-crystal televisions (LCTVs) that vary with the driving gray-scale level is presented. The theoretical derivation of the method is described. Compared with previous methods of measuring the phase shifts of LCTVs, this technique is noninterferometric and very simple. The experimental results of a LCTV are shown. (C) 1998 Optical Society of America. [References: 24]
