上海市激光技术研究所研制的共振式扫描器最近通过鉴定。 RI-5型共振式振镜结构独特,工艺新颖。它由一个安装在轴承上的板状软磁铁转子、软磁铁芯定子及永久磁钢组成。偏转频率高达1000 Hz,偏转角度可达±(7°～10°),频率及幅度稳定度均小于5％,为国内首次研制成功。通过对比测试,其主要性能指标已达到80年代末瑞士
The resonant scanner developed by Shanghai Institute of Laser Technology recently passed the appraisal. RI-5 resonance galvanometer unique structure, novel technology. It consists of a plate mounted on the bearing soft-magnet rotor, soft-core stator and permanent magnet composition. Deflection frequency up to 1000 Hz, deflection angle up to ± (7 ° ~ 10 °), the stability of the frequency and amplitude are less than 5%, for the first time successfully developed. Through the comparative test, its main performance indicators have reached the late 80s Switzerland
