一九八○年七月二十八日一八月一日,国家测绘总局在北京召开了电致发光(Electroluminsence缩写为EL)在CLY型立体量测仪(见图1)上的应用技术鉴定会。鉴定了上海测绘处采用我院电致发光研究室研制的固体平面冷光源——电致发光屏。会议认为电致发光屏具有成像清晰,立体效应强,光色柔和,观看舒适、保护视力,测量精度和工作效率较高等
On August 28, 1980, on August 1, the State Administration of Surveying and Mapping held a technical appraisal of the application of electroluminescence (Electroluminsence abbreviated as EL) on the CLY stereometer (see Figure 1) in Beijing meeting. The Shanghai Institute of Mapping identified the use of our Institute of electroluminescent research and development of solid planar cold light source - electroluminescent screen. Meeting that the electroluminescent screen with imaging clarity, strong stereoscopic effect, soft light color, viewing comfort, protection of eyesight, measurement accuracy and higher work efficiency
