最近,中国计量科学研究院西南分院、上海市标准计量管理局、中国计量科学研究院、宁江机床厂、上海科学仪器厂和云南光学仪器厂紧密协作,联合研制成功了我国第一台检测高精度量块的激光量块干涉仪。实现了100毫米以下量块自动测量和大量块高精度测量。经国家鉴定:仪器具有精度高、测量效率高(与柯氏干涉仪相比至少高十倍)、操作方便等优点。仪器将投入全国基准量块和一等标准量块的量值传递工作。
Recently, China Institute of Metrology Southwest Branch, the Shanghai Municipal Bureau of Standards Metrology, China Institute of Metrology, Ningjiang Machine Tool Plant, Shanghai Scientific Instrument Factory and Yunnan Optical Instrument Factory in close collaboration, the successful development of China’s first test high Accuracy of the block laser block interferometer. To achieve the following automatic measurement of 100 mm block and a large number of blocks of high-precision measurement. Identified by the state: the instrument has high accuracy, high measurement efficiency (compared with Korotkoff interferometer at least ten times higher), easy to operate and so on. The instrument will be put into the national standard block and first-class standard block mass transfer work.
