Abstract

The profile of the interference fringe packet obtained in a white light interferometer (WLI) may be dramatically altered by the so-called “fringe beating effect”, as a result, the peak value of the central fringe will 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.
