  1. Today, liquid crystal, a new functional material, has been applied more and more widely. on the side of display, owing to stable frarne, absolute environmental protecting, save electric energy and no tire for user, liquid crystal display keeps ahead among the range of display. with the developing of the technology of liquid crystsl, lcd will must substitute for crt and become the chief in market. in additin, liquid crystsl light filers which have been used in optic communicatins and light information handling, emply th e technical of combining the birefringence of liquid crystsl and fabry - petrot - type cavity. they manifest a series of merit, such as narrow band wide, deterioration low, wide tuning domain, simple structure and low cost, so liquid crystal light filter draw attention of many country

    現在,液晶作為一種新型功能材料越來越得到廣泛的應用,在電子顯示裝置中,液晶顯示器以其畫面平穩、真正安全環保、省電和使用者不易疲勞等優點領先於顯示器的行列中。隨著液晶技術的發展,液晶顯示器將取代crt顯示器逐步成為未來市場的主流。此外,應用於光通信和光信息處理中的電調諧液晶濾光片,採用液晶材料的雙折射和電光效應與傳統f - p腔相結合,表現出窄帶寬、低損耗、調諧范圍寬、驅動電壓低、結構簡單、低成本等一系列優點,而日益受到各國研究部門的關注。
  2. The tunable performance is obtained by rotating the grating. the disadvantages of the mechanical tunable filter are high control voltage, slow response time and big volume. the electro - optic tunable filters are obtained by the alteration of the birefringence of the electro - optic material applied voltage

    電子光學濾光片則是通過施加電壓使各種電子光學材料的雙折射率發生變化來實現透射波長的調諧,也可以利用電光晶體在電場中的旋轉來實現波長的調諧。
  3. The paper has five sections include the basic knowledge and the experiment research, systematically analyses the impact of the liquid crystal box ' s position angle on the measuring result of liquid crystal lyot filter and the practical significance of this work. the work of this paper maily includes five sections : ( 1 ) the related theory of the crystal birefringence is systemicly introduced in this paper ; ( 2 ) the theory of the lc voltage - dependent birefringence is introduced ; ( 3 ) no voltage applied, changing curve between the transmission and the liquid crystal box direction is got from experiment ; ( 4 ) voltage applied, changing curve between the transmission and the liquid crystal box direction is got from experiment ; ( 5 ) desired wavelength is extract from changing the direction of liquid box. originality innovation of this paper is that the theory of the lc voltage - dependent birefringence is systemically introduced in this paper especially those related to voltage and direction

    本文主要完成以下幾方面工作: ( 1 )比較系統地整理了晶體雙折射的有關理論; ( 2 )簡單介紹了液晶的電控雙折射特性; o )在未加電壓情況下,研究液晶盒方位角對濾光片透過率曲線的影響;廠)在加交流電壓的情況下,研究液晶盒方位角對濾光片透過率曲線的影響; ( 5 )利用方位角的調整來提取特定波長的譜線;本論文的創新之處在於比較系統地整理了晶體雙折射的有關理論,特別是與電壓及方向有關的理論,實驗得出了濾光片透過率隨液晶盒方位角變化的關系曲線,並將之運用於v吸器波長的話線朋
