摘要

光栅光阀(GLV)是一种衍射MOEMS空间光调制器，通过调制激光束已成功应用于计算机到光板(CTP)系统。提出了一种简化的光栅光阀光学模型，并根据弗劳恩霍夫单缝衍射理论和多光束干涉理论分析了光栅光阀的光学特性。介绍了光栅光阀在热CTP系统中的应用，分析了GLV光写入引擎的结构和成像原理。总结了基于glv的热CTP系统的数字成像过程，为国内印刷企业使用热成像技术提供了理论依据。

Optical characteristics analysis of grating light valve and application in thermal CTP system

The grating light valve(GLV)is a diffractive MOEMS spatial light modulator,and it has been successfully applied in the computer-to-plate(CTP)system by modulating laser beams.A simplified grating light valve optical model is put forward,and the optical characteristics of GLV is analyzed according to Fraunhofer single-slit diffraction theory and multiple beam interference theory.The application of grating light valve in thermal CTP system is described,and the structure and imaging principle of GLV optical write engine are analyzed.The digital imaging process of the GLV-based thermal CTP system is concluded,which provides the theory basis for the domestic printing enterprise to use the thermal imaging technology.

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
