An interferometric displacement sensor employing fiber optics has been built and tested. Since light is constrained to propagate through the fiber, the sensor can detect length changes of arbitrarily complicated paths, as a fiber stretches or contracts. Resolution, precision, and stability are discussed, with some possible applications. Agreement with elastooptic theory is very good.
