چکیده
This paper describes a fiber-optic temperature sensor that uses a spectrum-modulating Sic etalon. The spectral output of this type of sensor may be analyzed to obtain a tem.+ perature measurement which is largely independent of the transmission properties of the m sensor's fiber-optic link. A highly precise laboratory-type spectrometer is described in detail, and this instrument is used to study the properties of this type of sensor. Also described are a number of different spectrum analyzers that are suitable for use in a practical thermometer. v) h

Fiber - Optic Sensing of Linear Thermal Expansion (RESEARCH NOTES)
The use of a LED fiber-optic sensor to measure displacement and linear thermal expansion is described. It has a sensitivity of about 0.6 mV/mm, a resolution of 1.25 mm, and a dynamic rang of 400 mm for displacement measurements. For thermal expansion, it shows a sensitivity of about 3.5 mV/C, and the experimental linear expansion values are in agreement with those calculated. The reported senso...
