英文摘要	The data quality of wrapped phase play a very important role in phase unwrapping. The traditional filtering algorithms change jagged shapes of discrete phase point position. A novel filtering method based on trigonometric functions, intensity modulation and phase derivative variance is proposed in this paper, which can effectively filter noise of the wrapped phase data. Experimental results show that the algorithm can not only effectively filter the noise in wrapped phase data, but also to maintain value and position at the 2 pi jumps in the wrapped phase.
