利用象限测量器研制了一种新型光纤位移传感器，并利用该传感器测定了钢丝的弹性模量，实测值和标准值吻合较好．该传感器能广泛应用于微小位移、形变等的高精度测量． A new type of optical fiber displacement sensor was developed by means of quadrant measuring instrument. The elastic modulus of the steel wire was measured by this sensor. The measured value is in good agreement with the standard value. The sensor can be widely used in small displacement, deformation and other high-precision measurements.
