摘要：

A novel technique of using a three-wavelength combination source in white-light interferometry (WLI) to simplify the central fringe identification is presented. It is found that, by using this technique, the minimum signal-to-noise ratio required by the system to identify the central fringe position can be further reduced when compared with the use of two wavelength combination sources. This technique is simple and effective and has potential uses in coherence-multiplexed interferometric sensor systems.
