Abstract: An apparatus for detecting a gas having distinct infrared radiation absorption characteristics. The apparatus includes a spectral source/bolometer for conducting an electrical current and for producing an infrared radiation. The source/bolometer is disposed along an axis and has a temperature and a characteristic resistance, and the characteristic resistance is a predetermined function of the temperature. A return reflector is disposed along the axis beyond the gas such that at least a portion of the infrared radiation passing through the gas is reflected back through the gas to the source/bolometer. The apparatus also includes a driver/detector for driving a current through the source/bolometer, for determining the characteristic resistance, and for detecting the gas from a variation of the characteristic resistance.

Abstract: A temperature sensor for measuring a temperature of a substrate in a thermal processing chamber is described. The chamber includes a reflector forming a reflecting cavity with a substrate when the substrate is positioned in the chamber. The temperature sensor includes a probe having an input end positioned to receive radiation from the reflecting cavity, and a detector optically coupled to an output end of the probe. The radiation entering the probe includes reflected radiation and non-reflected radiation. The detector measures an intensity of a first portion of the radiation entering the probe to generate a first intensity signal and measures an intensity of a second portion of the radiation entering the probe to generate a second intensity signal. The detector is configured so that a ratio of the reflected radiation to the non-reflected radiation is higher in the first portion than the second portion. The two intensity signals are used to calculate the temperature and emissivity of the substrate.

Abstract: A waveguide for tympanic thermometer formed by an elongate hollow member having substantially ellipsoidal shape truncated at both ends along its major axis direction. The waveguide is interposed between a tympanic membrane of which the temperature is to be measured and an infrared radiation sensor so as to guide the infrared radiation from the tympanic membrane to the sensor. Alternatively, the waveguide may also be a hollow member including an end portion having a gradually reduced inner diameter toward the side of sensor. The gradually reduced end portion is preferably of a truncated half ellipsoidal shape having a length between about 1/10 to about 1/3 of the distance from the sensor to the distal end of the waveguide.

Abstract: A passive infrared motion detector with a 360.degree. field of view. The motion detector includes an integrated-circuit infrared sensor package containing an infra-red sensor having one or more sensing elements. The integrated-circuit sensor package is provided with viewing windows on both sides and the sensing elements are mounted within the integrated-circuit package so that both sides of the sensing elements are able to receive infrared radiation through the viewing windows from the areas in front of and behind the integrated-circuit package. The motion detector includes infrared-refracting means that are disposed with respect to the front and rear surfaces of the sensing elements so as to direct radiation to the surfaces from lateral areas on both sides of the integrated-circuit package. The infrared refracting means are positioned to leave at least a portion of the surfaces on both sides of the sensing elements unobstructed for receiving infrared radiation directed at the respective unobstructed portions from the frontal and rear regions of the field of view. A focusing means is provided to direct infra-red radiation from a plurality of zones in the frontal and rear regions of the field of view directly to the unobstructed portions of the sensing elements and from a plurality of zones in both lateral regions of the field of view to the refracting means for refraction to the sensing elements.

Abstract: Apparatus for measuring the value of the directional spectral hemispherical reflectance of the surface of a target when not engaging but being spaced from the target employs a hollow elongated member having a longitudinal axis and first and second opposite ends. The area of the first end is relatively large relative to that of the second end. The first end is open. The member has an inner chamber extending between the ends and has an inner surface adapted to reflect light falling within a specified wave band. The member when the apparatus is in use is positioned with the first end adjacent but spaced from a selected portion of the surface of the target. The longitudinal axis is oriented essentially normal to a region on the selected surface which would be engaged by a line coincident with the axis and sufficiently extended outwardly from the first end. A beam of light falling within said band is directed within at least a portion of the chamber along the axis and outward through the first end to impinge upon the selected surface portion. A portion of the beam is reflected after said impingement backward through the first end into the chamber. The reflected light which strikes the inner surface of the chamber is directed backwardly within the chamber toward the second end. An electrical signal derived from at least a portion of the backwardly directed light provides a measurement of said reflectance value.

Abstract: It is a problem of pyrometric temperature measuring of melts in a vacuum that the material of the melt will be deposited on mirrors, windows and other optical devices so that the radiation will be screened more and more effectively, the closer it comes to the pyrometer. In order to avoid vapor desposition in the path of radiation, a grating arrangement is provided between the melt and the pyrometer, which focusses the incoming radiation and concentrates it onto the pyrometer. The grating arrangement is partly permeable to the molecules of the melt material. The direct path between the melt and the pyrometer is blocked by a screen. In this way, vapor deposition on the window prefixed to the pyrometer are avoided, while the radiation can reach the pyrometer.

Abstract: A light collection device for use in a flame emission detection system such as an on-line, real-time alkali concentration process stream monitor is disclosed which comprises a sphere coated on its interior with a highly diffuse reflective paint which is positioned over a flame emission source, and one or more fiber optic cables which transfer the light generated at the interior of the sphere to a detecting device. The diffuse scattering of the light emitted by the flame uniformly distributes the light in the sphere, and the collection efficiency of the device is greater than that obtainable in the prior art. The device of the present invention thus provides enhanced sensitivity and reduces the noise associated with flame emission detectors, and can achieve substantial improvements in alkali detection levels.
