摘要： In an infrared imaging device, shutting means 40 is configured so that it can be opened/closed and so as to shut off an infrared radiation coming into an optical system 20 when it is closed. During an imaging operation, the shutting means 40 is opened, and the optical system 20 causes an infrared radiation from an object 70 to form an image on an infrared detector 10 . The infrared detector 10 outputs a signal according to the amount of infrared light received by each pixel. Correction means 30 corrects sensitivity variations among pixels, the influence of the infrared radiation from the optical system 20 , etc. During a calibration operation, the shutting means 40 is closed, and the correction means 30 determines a correction coefficient for correcting fluctuations in the amount of infrared radiation from the optical system 20 by using the output of the infrared detector 10 imaging the shutting means 40.

摘要： A radiation clinical thermometer for making no-contact measurements of the temperature of the eardrum, comprising a light receiving section (17) for receiving only infrared rays radiated directly from the eardrum and/or its vicinity, a signal processing means (4) for calculating the temperature from the output of the light receiving section, and an annunciation means (18) for annunciating the calculated temperature. Because the thermometer is not influenced by the heat radiation from other than the eardrum and/or its vicinity, the temperature variation of the probe (1) does not cause measurement errors and therefore an accurate temperature measurement can be made. When viewed at the cross section of the thermometer including the optical axis of the light collecting element, the infrared light receiving element is placed in a triangle formed by three lines connecting three points, and an intersection between the optical axis of the light collecting element and an optical path where a line drawn from the edge of the light collecting element in such a way as to be tangent to the inner wall of the probe on the same side as the edge of the light collecting element with respect to the optical axis extends from an imaginary end where the line intersects the end surface of the probe and passes through the edge of the light collecting element on the same side as the imaginary end point with respect to the optical axis to reach an image point of the imaginary end point by the light collecting element. The remaining two points are two image points of the light collecting element at the imaginary end point.

摘要： Disclosed is a radiation detector which includes a photoconductive detector (8) and a modulator (4) which modulates radiation (6) passing to the photoconductive detector (8) from a radiation source (2). An AC bias source (10) is connected to the photoconductive detector (8) and provides at least two levels of bias thereto. The modulator (4) supplies synchronization signals (14) to the AC bias source (10) such that the level of bias supplied to the photoconductive detector (8) is synchronized to the modulation of the radiation (6) by the modulator (4). An integrator (20) is connected to and receives an output signal generated by the photoconductive detector (8).

摘要： A disc having a plurality of radial slits of a width substantially equal to the photosensitive diameter of a sensor and a rotary chopper are rotatably disposed on the same axis, and the disc and the chopper are rotated at their respective speeds so that an infrared beam passing through a slit opposed to a sensor may be interrupted (2 to 16) times by the chopper. Two or more sets of infrared sensors for different wavelength bands are disposed radially behind the chopper and the disc, and a zone to be monitored is scanned in X and Y directions to obtain detection signals. In this way, it becomes easy to recognize at which position inside the field of view fire occurs, and even when the fires occur at a plurality of positions, they can be detected discriminatingly.

摘要： A disc having a plurality of slits radially each of which have approximately the same width as a diameter of a photoreceptor of the sensor, and a rotary chopper, are arranged to coaxially rotate. When one of the slits faces a sensor, the disc and the chopper are rotated at a rotational speed so that the incident infrared radiation into the sensor is chopped 2-16 times by the chopper. At least two sets of sensors, each set of which comprises a plurality of sensors for sensing infrared radiation of different wavelength bands to one another, the sensors being arranged behind the chopper and the disc along a radial direction centered at the rotational axis of the chopper, are provided. Accordingly, because detection signals by scanning a monitored area in a X-direction and a Y-direction respectively are obtained, it is possible to easily recognize the position where the disastrous fire occurs in the visual field and to detect positions of disastrous fires in distinction from one another even if those occur at a plurality of positions.

摘要： Bei einem Strahlungssensor (11) wird die auf einem pyroelektrischen Sensor (16) einfallende elektromagnetische Strahlung (14) periodisch unterbrochen. Hierzu ist im Fuß (24) einer Umlenkeinrichtung (25) ein Anker (22) mit an den beiden Stirnseiten befestigten Permanent­magneten (23) angeordnet. Wird der Stromfluß in der Spule (19) periodisch geändert, so führt der Anker (22)eine entsprechende periodische Bewegung aus. Dadurch wird mit Hilfe eines Arms (26) an der Umlenkeinrichtung (25) der Strahlenfluß zum pyroelektrischen Sensor (16) unterbrochen, um so ein elektrisches Ausgangssignal zu erhalten. Der Sensor (11) baut besonders einfach und kann aus wenigen Bauteilen als Serienprodukt hergestellt werden.

摘要： A method and apparatus for determining the temperature of a hot body by a non-contact technique. It comprises a chopping disc (2) which may be disposed in the path of the radiant heat energy from the object so providing a pulsed output of radiant heat energy directed towards a pyroelectric element (7). Between the pyroelectric element (7) and the disc (2) is a further rotatable disc (4) having a pair of wavelength filters (6 and 6'). A microprocessor (14) operates to rotate the disc (4) to interpose each filter (6 and 6') in turn in the path of the pulsed output from the disc (2) at predetermined time intervals. The consequent output from the pyroelectric element (7) is, after amplification, rectification and smoothing in suitable circuits, fed to the microprocessor (14), which then calculates the ratio of the signal from the element (7) representative of power output through one of the filters, and the signal from element (7) representative of power output through the other filter. In this way the temperature of the hot body is determinable without prior knowledge of the emissivity characteristics of the hot body.

摘要： A shutter assembly comprising a first planar member and a second planar member opposed from one another and forming a sleeve having a cavity therebetween, the sleeve having a pair of side rails adjacent the cavity along sides of the sleeve. A first shutter member having a first end is disposed in the cavity and slidingly disposed along one of the side rails, and a second shutter member having a second end is disposed in the cavity and slidingly disposed along the other side rail. The first end is opposed to the second end and is configured to be selectively advanced towards, and retracted from, the second end so as to define an aperture therebetween having a first shape when disposed in a first position, and wherein the aperture has a second larger shape when the first end is disposed in a second position. The first shutter member and the second shutter member maintain a thermal contact with the side rails and the planar members in all positions. The shutter assembly is well suited to be used at a cryogenic temperature and in a high vacuum environment.
