1.测量原理光纤位移测量仪是一种用光学杠杆原理来测量化移、振动以及表面状态的非接触式量仪。通过光纤探头,仪器既可发射光束,又可接收目标表面的反射光,并将反射光转换成与目标距离成比例的电信号。其输出电压即可反映目标表面的位置、位移、振幅、频率及波形。仪器的工作原理如图2和图3所示。当探 1. Measuring principle Optical fiber displacement measuring instrument is a kind of non-contact measuring instrument which uses optical lever principle to measure shift, vibration and surface condition. With a fiber optic probe, the instrument emits both light and reflected light from the target surface and converts the reflected light into an electrical signal proportional to the target distance. Its output voltage reflects the position, displacement, amplitude, frequency and waveform of the target surface. The working principle of the instrument is shown in Figure 2 and Figure 3.
