- This article discuss the method to measure distortion of truss by means of ccd device . the distortion can be measured with many kind of displacement transducer , but it must be placed on stable base . when the huge truss is moving through some tunnel , it is difficult to find a stable base , especially there is no enough space for someone to operate . it is hardly to measure the distortion by touching . on the contrary , this can be achieved by means of ccd device
桁架在自重或载荷的作用下产生的挠度可以用多种位移传感器测得，这些测量方法需要有良好的基础，在大型桁架梁测量现场，由于桁架的变形，难于找到这种基准，如果加上测量环境恶劣，人无法操作情况，则会给挠度测量带来极大的困难，而采用光电荷耦合器件，并利用激光进行远程实时挠度测量，即可以解决这个难题。
