Title: System for accurately detecting change in temperature and pressure
Inventor: BIKUTAA BARI
IPC: G01K11/12
Filed: 1991-12-24
Abstract: PURPOSE: To detect fluctuation of temperature and pressure accurately by providing an optical means including pressuresensitive and temperature-sensitive optical fibers producing an optical signal indicative of temperature fluctuation over a first optical frequency band and an optical signal indicative of pressure fluctuation over a second different optical frequency band, respectively. CONSTITUTION: An optical fiber interferometer 1 comprises a laser light source 2 connected with an optical path 3 being split into two optical paths 5, 6 through a beam splitter 4. A light from the optical path 5 is guided through a reference coil 7 and an optical path 8 to a detector 9 while a light from the optical path 6 is guided through a sensor coil 10 and an optical path 11 to the detector 9. The difference between optical signals outputted from the coils 7, 10 appears in the detector 9 as a shift of optical fringes. It is a function of the temperature and pressure being applied to the coil 10 or the fluctuation thereof. The coil 10 is mounted on the outer wall of cylinder of an internal combustion engine, for example, and responds to fluctuation of the temperature and pressure of the cylinder.  The fluctuation is detected by the detector 9 as a shift of fringes when the light from the optical path 11 interferes with the light from the optical path 8.
