一九八○年七月底,国家测绘总局在北京召开了我院电致发光研究室研制的电致发光屏在 LCY-1立体量测仪上应用的技术鉴定会。近年来,国内外在测绘仪器中都有一个明显的趋势,即大力普及、推广用涤纶片基的感光软片代替传统裱版象片,这在电算加密,象片纠正和提高作业精度等方面都有显著的优点。但立体量测仪这类仪器,由于一般都采用反射式白炽灯光源,只适于
By the end of July 1980, the State Administration of Surveying and Mapping held a technical appraisal meeting of the electroluminescent screen developed by the Electro-Luminescence Laboratory of our institute on the LCY-1 stereo measuring instrument in Beijing. In recent years, there is a clear trend both at home and abroad in surveying and mapping instruments that vigorously popularize and promote the use of photosensitive film based on polyester film instead of the traditional mounting plate, which in terms of computer encryption, image correction and improve work accuracy There are significant advantages. However, three-dimensional measuring instrument of this type of instrument, as a general use of reflective incandescent light source, only suitable
