Overview
ABSTRACT
A large number of measurement devices incorporate an optical fiber. This article reviews the set of measurements in which an optical fiber is incorporated: mechanical (displacement sensors), electric (voltage sensors), magnetic and nuclear, up to thermometers (spectral analysis) and chemical sensors (alcane vapor sensors). Following is a description of devices using optical fiber control; the operation of presence sensors, endoscopy and qualitative control.

The development of fiber optic sensors is hampered by a psychological factor. All too often, buyers mistakenly believe that optical components are fragile, that they need to work in a clean environment. As a result, the market is small, limited to a few technological niches, mainly due to a lack of information among potential users
