Abstract
An optical temperature sensor and method of manufacture therefor in which the intensity of light reflected from a first dielectric interface or from first and second dielectric interfaces, wherein one of the dielectrics has a temperature dependent index of refraction is measured. The intensity of light refleted from such dielectric interfaces will vary depending on the index of refraction which in turn is temperature dependent, thus providing a temperature dependent light signal.
