实验室液晶光开关演示装置的研制

Development of liquid crystal optical switch for experiment demonstration

通过研究液晶光开关，改进制作了一个成本低、工艺简单的实验室演示装置。初步达到了在实验室演示光开关工作原理的目的，并通过实验力求了解向列相液晶光开关的一些特性。

The paper introduces the demonstrative device with low cost and simple technology, using for laboratory on the basis of developing a liquid crystal optical switch. The device reaches the target of demonstrating the principle of optical switch in the laboratory, and the characteristic of the nematic liquid crystal optical switch is easy to be understood through the experiment.
