We describe in this paper a pilot experiment of optimization of a white-light source for low-coherence interferometry. The white-light source combines the light beams generated with color LEDs. By modeling of the white light spectra, a contrast of a white light interference fringe could be changed and set to the maximal value. The optimized white light source is designed to be a crucial part of an experimental setup for surface diagnostics and automatic calibration of gauge blocks. This paper also describes the concept of the light source combining white-light beam and laser beam, based on fiber optics.
