    Abstract: This invention relates to apparatus for sensing, remotely, the temperature of a semi-conductor wafer and includes means for shining a single frequency light 11 onto the surface 12 of a semi-conductor wafer 13 so that some of that light is scattered. The scattered light is focused by a lens 15 and the single frequency is filtered out of the scattered light by notch filter 17. The filtered beam is split by beam splitter 18 and the resultant two beams are filtered so that they respectively pass only the Stokes and anti-Stokes frequencies respectively. The intensities of these respective light beams are then measured and from these the temperature of the semi-conductor wafer is calculated.

    Abstract: A blackbody high temperature probe is formed by thermally fusing a coating of composite ceramic material on the tip of a high temperature lightpipe or fiber. The ceramic coating replaces conventional sputtered metallic thin films to form a blackbody optical cavity. The ingredients of the composite ceramic material include a mixture of refractory metal oxides forming the bulk of the material, various pigments and/or refractory metal powders, and binding agents. A firing process is used to thermally fuse the coating onto the lightpipe. Embodiments of the firing process include using a flame or furnace technique, or alternatively using various flame- or plasma- spraying techniques. A thermally fused coating of from 10 to a few hundred micrometers provides a durable blackbody temperature sensor suitable for use in a wide range of applications including measurements in high temperature, high flow rate and abrasive environments such as that encountered in an internal combustion engine, gas turbine or rocket exhaust stream.
