In low-coherent measurement techniques coherence function of the source affects metrological parameters of the designed system. Hence, in many applications, it is necessary to use some techniques to change the shape of coherence function of the source. It is possible to do so by the use of optic, mechanic and electronic methods. In this article, author analyses the possibilities of shaping the coherence function of the optic source by the use of optic methods. The result of theoretical investigation and simulations will show that the use of the source with shaped coherence function can improve the metrological parameters of the designed system.
