We report a novel frequency multiplexing method for addressing low finesse fiber Fabry–Perot sensors using a white light source and a CCD based monochromator. The absolute optical path length imbalance of the sensors can be determined using this method. The concept was demonstrated with three fiber Fabry–Perot interferometers for strain and displacement measurements. The accuracy is better than 0.01 μm and the maximum range is approximately 1 mm. © 2000 American Institute of Physics.
