This method place some linear array CCD as a high benchmark test at various location for measurement, and use of the laser as line source so that the linear array CCD of different positions receives the same signal of beam light at the same time. Then, linear coordinate transformation is used to transfer location information of height which array CCD receives into elevation output whose baseline is coincident with other coordinate. Compared with each value data in different load conditions or at different moments at last, real-time relative deformation of points is in the platform. The method brings about good results in practical application. words: large-scale platform; deformation; photoelectric measurement; linear array CCD /d494118543.html 引 言 当前关于各类平面变形量自动监测的方法种类很多，有机械式、磁电式、光学式、光电式等。机械式 测量方法以各类卡尺的卡量为典型手段
