Paper Abstract

The output intensity distribution from a white light interferometer (WLI) may be varied if the quality of the collimation lens used is poor or the alignment of the optical arrangement is not good. This effect will make the peak value of the central fringe be equal to or even less than that of the other fringes, and in consequence the WLI scheme will give an erroneous result for the determination of the central fringe position. This effect is analyzed theoretically using a computer simulation model, and the results from both the computer simulation and experiment are discussed and compared.
