Intensity modulation induced by macrobending in multimode optical fibers is presented as a transduction mechanism for analog position sensing in harsh aerospace environments. The macrobend sensor described herein is most suitable for short stroke applications (1 to 10 mm) where an intrinsic sensor is desired and only moderate linearity is required (< ± 1 %). Macrobend sensors are built and tested with intensity referencing and modal conditioning. The latter allow for sensor replacement without in-situ calibration. The theory, design tradeoffs, and test results of generic intrinsic macrobend position sensors are presented.
