摘　　要：设计了一套单缝衍射条纹图像实时采集系统,通过把挠度转换为单缝宽度的变化,实现了对梁弯曲时微小位移的测量,并用实验证明了该方法的有效性和实用性.By designing an acquiring system of real-time stripe image from single slit diffraction and conversing the deflection to the change of width of single slit, this paper realizes the measurement of tiny displacement of girder during the period of bending and demonstrates the validity and practicality of this new method.
