Abstract: A fiber optic sensor, a process for utilizing a fiber optic sensor, and a process for fabricating a fiber optic sensor are described, where a double-side-polished silicon pillar is attached to an optical fiber tip and forms a Fabry-Pérot cavity. In an implementation, a fiber optic sensor in accordance with an exemplary embodiment includes an optical fiber configured to be coupled to a light source and a spectrometer; and a single silicon layer or multiple silicon layers disposed on an end face of the optical fiber, where each of the silicon layer(s) defines a Fabry-Pérot interferometer, and where the sensor head reflects light from the light source to the spectrometer. In some implementations, the fiber optic sensor may include the light source coupled to the optical fiber; a spectrometer coupled to the optical fiber; and a controller coupled to the high speed spectrometer.

Abstract: A flame detector includes a beam splitter to split mid-wave infrared radiation (MWIR) and long-wave infrared radiation (LWIR) into an MWIR component and an LWIR component. An MWIR detector detects the MWIR component and an LWIR detector detects the LWIR component. The flame detector analyzes the MWIR component to determine the presence of a flame and analyzes the LAIR component to determine whether the system is functioning properly.

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.
