Recently, high precision fiber displacement sensors have received significant attention for applications ranging from industrial to medical fields that include reverse engineering and micro-assembly (Laurence et al.

In this chapter, fiber-optic displacement sensors (FODS) are demonstrated using an intensity modulation technique. These features make OFDSs ideal for use in confined spaces, such as turbines, where direct laser access is.
