Fiber-Optic Thermometers:
These instruments enable near-infrared and visible radiation
to be transmitted around corners and away from hot,
hazardous environments to locations more suitable for the
electronics associated with contemporary radiation
thermometers. Fiber optics also makes possible measurements
in regions where access is restricted to larger instruments
and where large electric or radio frequency fields would
seriously affect an ordinary sensor. Conceptually, a
fiber-optic system differs from an ordinary IR thermometer
by the addition of a fiber-optic light guide, with or
without a lens. The optics of the light guide defines the
field of view of the instrument, while the optical
transmission properties of the fiber-optic elements form an
integral part of the thermometer spectral response.
