A new fast 3D p rofilometry is presented in this paper. Three lines CCD arrays, 1024 pixels each, are mounted togetherwith the same distance intervals. Needless to perform phase shift operations, the CCD can consecutively scan and grab 3 phase distributed p ictures which will be separately calculated by 3 DSP processors. Thus the whole measurement process is finished. The experimental results show that the phase measurement system by using 3 lines CCD has high app lication values for its high precision and speed.
