Electrical voltage can be sensed by nonlinear optical effects in specially-doped fiber, which alter the polarization of light as a function of voltage or electric field. Interventional pulmonology is the facet of modern medicine tasked with detecting, diagnosing, and treating illnesses and diseases in this area. These intra-body devices can be shown in the context of the patients anatomy through integration with images obtained by conventional pre- or intra operative techniques (CT, MRI and X-ray fluoroscopy respectively). The fotonic sensor, an extrinsic fiber sensor used for non-contact vibration measurements, was patented in 1967.
