英文摘要：

Based on Twyman--Green laser wave interference principle and polarized phase shifting technology, synchronism phase--shifting interference technology was put forward,and a synchronism phase--shifting interferometry with excellent anti--vibraion characterisics was investigated, so that on --line precision surface measurement and quality monitoring problem can be solved. The synchronism phase--shifting interference principle for surface measurement was introduced, its anti--vibration characteristics was analyzed, an experimental system was setup, and testing experiences were conducted. Analysis and experimental testing results show that the synchronism phase--shifting wave interferometry is suitable for on--line precision surface measurement.
