Synchronous measurement of six-dimensional vibration displacements is difficult because of their coupling.A new method for the measurement was introduced in this paper.Two little novel light-reflectors were used in the sensor system to convert the displacements into corresponding displacement and shape information of two light curves.Six sets of CCD devices were used to covert the information into electrical signals,which were sent into a computer by a data acguisition board for processing to obtain the reguired displacements.
