Abstract

An optical temperature measurement sensor utilizes the decay fluorescent characteristic of ruby crystal that is excited to luminescence by a light emitting diode source (excited light source). The sensor measures over a temperature rang of 20 - 170 °C with accuracy between ~ 0.03 and ~ 0.15 °C.
