为了研究索尼LCX029 CRT液晶显示器纯位相调制特性,设计了索尼LCX029 CRT液晶显示器的驱动电路,并搭建了测试光路对其纯位相调制特性进行了研究,同时对光路进行了理论分析。实验获得一组移动的干涉条纹,实验测试研究结果表明索尼LCX029CRT液晶显示器具有π/2的相位调制特性。

In order to study the pure phase modulation characteristics of Sony LCX029 CRT liquid-crystal display(LCD), the drive circuit was designed and the test optical path was set up to determination phase modulation depth of the LCX029 CRT. The theoretical analysis about the test optical path was also given. A group of mobile interference fringes were obtained. Experimental test results show that the phase modulation depth of the LCX029 CRT is π/2.
