Abstract: A method and apparatus for maintaining a viewing window of a detector substantially clean includes enclosing the detector within a housing, and moving a target surface relative to the viewing window to create an airflow adjacent the viewing window. The housing can include an aperture through which the viewing window of the sensor views the target surface. Motion of the target surface creates an airflow velocity adjacent the viewing window for maintaining the viewing window substantially clean. To increase the accuracy of the detector, a high emissivity area is provided on an outside surface of the housing which faces the target surface.

Abstract: A wave-collecting device of a non-contact type thermometer comprises a main body. An ellipsoid groove is disposed in the main body. The groove can be composed of at least two inclined planes. An opening is disposed at the bottom of the ellipsoid groove and located above a focus thereof. An ellipsoid reflecting mirror is disposed on the surface of the ellipsoid groove. A sensor is disposed below the opening at the bottom of the ellipsoid groove. The detection head of the sensor is located at the focus. In addition to being directly incident onto the sensor, infrared rays emitted by a target at the other focus of the ellipsoid groove can be reflected by the ellipsoid reflecting mirror once to be focused onto the sensor. Therefore, stable and reliable infrared energy reception can be accomplished. Moreover, the advantage of low cost can be achieved.

Abstract: Apparatus and a method for radiometric temperature measurement comprises a radiometer receiver coupled to an antenna/calibration switch that has coupled thereto a brightness temperature signal. A driver coupled to the antenna/calibration switch controls the operation of the switch between an antenna mode and a calibration mode. An adjustable cold/warm noise source is coupled to the antenna/calibration switch to provide a calibration radiation temperature applied through the antenna/calibration switch in the calibration mode to the radiometer receiver. An output of the radiometer receiver is coupled to the adjustable cold/warm noise source and is adjusted in accordance with the output of the radiometer receiver for a null comparison measurement. Also coupled between the output of the radiometer receiver and the antenna/calibration switch is a mode selector switch that operates to a mode one position to couple the output of the radiometer receiver to the adjustable cold/warm noise source. A bias source is also coupled to the mode selector switch and actuation of the mode selector switch into a mode two position couples the bias source to the adjustable cold/warm noise source.

Abstract: Methods and systems are disclosed for detecting overheating in an optical device before harmful consequences, such as severe local heating, can result. In one embodiment of the invention, a blackbody emitter is disposed in close proximity to a therapeutic optical fiber to absorb therapeutic radiation at a fault and re-emit blackbody (infrared) radiation. The emitter can be coupled to the fiber but, during normal operation, lies outside the optical path between the output of the laser radiation and the site of treatment. Systems and catheters incorporating such emitters are also described for effective monitoring of the laser power transmitted along the optical fiber within the phototherapy device.

Abstract: A body temperature detector is particularly suited to axillary temperature measurements of adults. The radiation sensor views a target surface area of the body and electronics compute an internal temperature of the body as a function of ambient temperature and sensed surface temperature. The function includes a weighted difference of surface temperature and ambient temperature, the weighting being varied with target temperature to account for varying perfusion rate. Preferably, the coefficient varies from a normal of about 0.13 through a range to include 0.09. The ambient temperature used in the function is assumed at about 80null F. but modified with detector temperature weighted by 20%.
