Abstract
A method of accurately determining the temperature of a thin layer of bandgap material without requiring contact to the layer involves the use of optical radiation reflected off the bandgap material and the detection of the reflected energy. The relationship between the temperature varying bandgap energy and the resulting reflection characteristics provides an indication of temperature, independent of ambient temperature.
