Ccd Deflection Measurement System

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.This measurement system includes three parts: the first is the CCD detector. It' s function is to receive laser signal and to sent out the electric signal; the second is the monolithic processor system .This part function is to pick up the electric signal sent by CCD detector and to compute the digital signal to get the data where the laser beamed , then sent the data to PC computer; the third part is the control interface for people to control whole measurement process. It is fast, accurate and easy to measure distortion with this measurement system.
