-Instrument Introduction

Liquid crystal is an organic polymer compound between liquid and crystal, which has both the fluidity of liquid and the orientation characteristics of crystal. When liquid crystal molecules are arranged in an orderly manner, they exhibit optical anisotropy. LCD screen is a spatial light modulator made by utilizing the modulation characteristics of liquid crystal for light. This modulator is electrically addressable, which facilitates the control of signal input and output through computers, and can also be used for optical information processing, such as computational holography. This product is suitable for optical basic experimental teaching in the fields of optoelectronic information engineering, physics, and related majors.
