Abstract: A surface profile measuring method using a broad bandwidth light source illuminating a sample surface and a reference surface through a splitter is provided. By changing a distance between the sample surface and the reference surface with a constant step, an interference diagram with a waveform composed of interference data points depicting a relationship of surface height versus illumination intensity is generated. In the beginning, a first data point with greatest illumination intensity is selected from the interference data points on the waveform. Then, a second data point is selected from the data points on the waveform within a predetermined range centered at the first data point to have the waveform showing best quality of symmetry. Then, a peak of a fringe defined by the second data point and its neighboring data points is estimated by using phase compensating approach.
