Abstract
The effect of nonlinear wavelength scanning to Fourier transform white-light interferometry was examined. A Mach-Zehnder interferometer was interrogated, and the absolute optical path difference was measured. The experimental results show that the nonlinearity of the Fabry-Perot tunable filter has no effect on the measurement. A measuring discrimination of 3 run is achieved.
