Abstract

We report the development of a novel hybrid optoelectronic system for temperature measurement based on the alignment response time of liquid crystals in a liquid crystal display (LCD). The LCD is incorporated as a transducer which is fully optically powered into a self-resonant system whose resonant frequency depends on the liquid crystal viscosity and hence on temperature. The frequency dependence on temperature is characterised. and the suitability of the system as a temperature sensor is discussed.
