Paper Abstract

In order to decrease the phase shift error, this paper presented a new object phase shifting method by using fringe stabilizing device to stabilize the interference fringe. The experimental result shows the fringe drift is less than ?/20 in five minutes , and the phase shifting precision is more than 0.004 ? , furthermore the system is very simple, performance reliable and operating convenience, it will take an important role for improving the measure precision of 3-D phase profilometry, more strong practicality and popularly application prospect.
