Paper Abstract

An optical fibre temperature sensor modified with coating a thermochromic liquid crystal (TLC) film on the tip of fibre is reported. The interrogation is conducted in the wavelength domain using a CCD spectrometer and halogen light source. The TLC sensor shows a reversible wavelength shift of the reflective light peak in the detected temperature range (28 – 46°C). The response of the sensor to temperature was linear with a sensitivity of -4.52 nm/°C for temperature increasing and -4.60 nm/°C for decreasing. There is no measurable hysteresis in the temperature calibration experiment for TLC sensor.
