摘　　要：将光载波技术应用到影象云纹法中，且推导出其解调公式，因而可以将载波一调制一解调这统一的方法用于云纹法，并将该法在沉箱闸结构模型试验中进行应用，对其交通桥桥面板位移进行测量，得到位移分布曲线。The authors apply successfully the photocarrier technique to the shadow moire method and de-rive the formula of demodulation. Therefore,the whole process of carrier wave,modulation and demodulationcan be used in the shadow moire method, and has been put to the application of model studies of structure ofcaisson gate. The displacement of face slab of communication bridge is measured and the distribution curve ofdisplacement is obtained.
