Abstract: In an infrared detector array according to the present invention, on a thin film with a periphery portion supported by a frame, three or more infrared detecting pixels are arranged in an array pattern so that the hot junctions of thermocouples are arranged above a concave portion and the cold junctions thereof are arranged above the frame. Compensation means is provided which compensates for a difference between the detection sensitivity of the infrared detecting pixel arranged in a peripheral end portion and the detection sensitivity of the infrared detecting pixel arranged in an intermediate portion based on a correlation between electromotive force extracted when the infrared detecting pixel is illuminated with infrared radiation and its position. Owing to this configuration, a plurality of infrared detecting pixels can be integrated and the sensitivity thereof can be made sufficiently high and uniform.

Abstract: A passive low power device for detection of boundary crossings includes a dual element pyro-electric infrared (PIR) sensor. The sensor is designed with a lens that provides a very narrow field of view and two pyro-electric elements that produce a waveform with two voltage swings of opposite polarity when a warm object moves past the sensor. The waveform is filtered and amplified before it is passed on to a comparator. The comparator triggers off the extremes of each waveform. The comparator includes two outputs that are normally high, but go low when a change in infrared radiation is detected. A processor makes an approximation of the zero crossing time based on the rising edge of the first comparator output. This approximate zero crossing time serves as an estimate of the boundary crossing time.

Abstract: The invention relates to an inspection method for inspecting the quality of a weld seam (15) during which a material, which is transparent to electromagnetic radiation (30) of a defined frequency, is used in a workpiece (10) consisting of two plastic parts (11, 12). In order to be able to reliably inspect the weld seam, the invention provides that an electromagnetic inspection radiation (30) is irradiated inside the workpiece (10). The resulting reflections between the boundary surfaces in the workpiece (10) and the portions of inspection radiation (30, 30null) exiting from the workpiece (10) are affected by the quality of the produced weld seam (15). By measuring the exiting radiation (33, 33null), it can be clearly determined whether the workpiece (10) has a defective or a tolerable seam (15).

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.
