摘　　要：介绍了一种光纤几何参数自动测量的新技术。利用图象扫描和脉冲计数方法获取光纤截面的边缘信息,用微机进行数据采集和处理,有效地提高了测量系统的分辨率和测量速度。实验结果表明:该测量系统的测量重复性达0.1μm,分辨率可达0.05μm,单个光纤试样的测量时间<1min。A new automatic technique for measuring geometric parameters ofoptical fibers has been developed.The resolution and the measurement speed have been greatly improved by using the image scanning and pulse counting as well as the microcomputer data acquisition and processing.Experimental results show that the repeatability(2σ)and the resolution of this method are less than 0.1μm and 0.05μm respectively.The total measurement time for one optical fiber sample is within one minute.
