Error analysis in the absolute phase maps recovered by fringe patterns with three different wavelengths

Journal Article


Abstract


  • In a recently published work, we proposed a technique to recover the absolute phase maps from the wrapped ones with three different fringe wavelengths. It was noticed that when the wrapped phase maps are obtained by three-step phase shifting method, errors in fringe order still occur, leading to significant error in the recovered absolute phase maps. In this paper, the┬ácharacteristic and reason of the errors are analysed, and a method to avoid these errors is also proposed. The theoretical conclusions in this paper are validated with experimental results.
