摘要:
The present invention is applied to an infrared imaging device including infrared lens (11) condensing infrared light, infrared sensor (12) detecting the condensed infrared light, and image signal output unit (18) eliminating fixed pattern noise for each pixel from an output signal from infrared sensor (12) and acquiring an image signal. The infrared imaging device includes sensor field-of-view controller (13) varying the field-of-view of infrared sensor (12) with respect to the infrared light incident on infrared sensor (12), and overall controller (16) acquiring the fixed pattern noise for each pixel on the basis of the luminance of the output signal from infrared sensor (12) when varying the field-of view of infrared sensor (12).

A testing device for testing infrared OFDs (370; 470; 570) is provided. The testing device (100; 200; 300; 400; 500) may comprise a body (110; 210), an infrared source (120; 220), a controller (150; 250) and a user input (140; 240). The infrared source (120; 220) may be housed with the body (110; 210). The controller (150; 250) may be operatively coupled to the infrared source (120; 220). The controller (150; 250) may also be integral to the infrared source (120; 220). The user input (140; 240) may be operatively coupled to at least one of the controller (150; 250) and the infrared source (120; 220). The testing device (100; 200; 300; 400; 500) may be configured to produce infrared emissions to simulate flaming fire.

A calibration system (300) for a detector (328) includes a base member (302), a plurality of radiation sources (304)fixedly attached to the base member, and a positioning mechanism (306) attached to the base member. Each radiation source (394) is maintained at a different temperature and is configured to emit electromagnetic radiation. The positioning mechanism includes a movable member (308) having a single degree of freedom with respect to the base member (302), and a plurality of optical elements arranged (310) on the movable member. Each optical element corresponds (310) to one of the radiation sources (304) and each optical element is configured to at least be movable between a calibration position and a non-calibration position. When the optical element is in the calibration position, the optical element is configured to receive the electromagnetic radiation from its corresponding radiation source and to reflect the electromagnetic radiation to a detector.

An optical system and a focusing structure for an infrared thermometer are provided. The optical system includes a focusing ocular barrel (100) and an objective focusing ring (300), provided at the rear end of an optical probe. By controlling the shift of the ocular (101) and the objective (201), the best visual collimation definition and the highest optical focus resolution of the system can be achieved without reducing the measurement precision. The rear end of the probe includes a cap (507), which can be used for locking the detective image distance of the objective (201) and sealing and protecting the portion of the focusing operation.

A non-contact measurement device includes two or more detectors for sensing scene data from corresponding measurement zones within a target scene. Devices further include an optical system for imaging scene data from the target scene onto the detectors. The optical system is configured to provide a different optical profile for each detector, such that the device can be used to provide a best-fit optical profile for a variety of non-contact applications.

摘要:
A temperature monitor for monitoring plural locations on an electrical bus structure. The temperature monitor includes an infrared sensor for receiving infrared energy from a plurality of discrete predetermined locations on the bus structure, a first member defining a stationary first mask, a second member defining a rotating second mask, and a drive member driving the second member in rotation relative to the first member. Rotation of the second member relative to the first member defines an aperture translated across the first mask member to provide a moving line-of-sight that extends from the sensor and that scans to each of the discrete predetermined locations on the bus structure.
