A fiberoptic system for clearance detection between rotating and stationary turbomachinery components is presented. The system comprises an optical fiber probe comprising a plurality of optical fibers, at least one of the optical fibers comprising a transmission fiber and at least one of the optical fibers comprising a signal fiber; a light source for providing light through the transmission fiber towards a target; filters for receiving light from the signal fibers, at least two of the filters for filtering different wavelengths; and at least one photodetector for receiving filtered light from the filters.
