A simplified white light correlator with a compensation grating has been developed and proved to be effective for particle sizing when high pass filtering is adopted during MSF fabrication. Both the theoretical analysis and experimental results are presented in this paper. By using this technique the soze of objects with the annulus shape can be determined to the accuracy within 1-2% relative error.
