A graphical user interface for configuring parameters associated with a portable infrared imager is provided. The interface can be used to manually or automatically set range and span parameters. The interface can also be used to configure one or more alarms to notify a user that a detected temperature is outside a predetermined range.

System and method for configuring a thermal imaging instrument

A graphical user interface for analyzing thermal images is provided. The interface can be used to identify the temperatures at multiple areas of interest defined on an image. The areas can be denoted by configurable markers of different predetermined shapes. In some embodiments, the interface simultaneously displays temperature statistics relating to the user-identified areas of interest.

System and method for analyzing a thermal image using configurable markers

An interactive graphical user interface includes a moveable pointer, which may be activated to select points of a computer-generated thermal image of an object, as the pointer is moved over a display of the image, so that line temperature profiles, which correspond to predetermined lines extending through the selected points, may be viewed, for example, on a line temperature profile chart of the interface, for each selected point as the pointer is moved. Each predetermined line extends between the corresponding selected point and another, predetermined, point of the image. The other predetermined point may either coincide with an origin of an x-axis or a y-axis of an orthogonal coordinate system, in which the image is aligned, or may be any other point of the thermal image, for example, one that is pre-selected by a user, with the moveable pointer.

A graphical user interface for configuring parameters associated with a portable infrared imager is provided. The interface can be used to manually or automatically set range and span parameters. The interface can also be used to configure one or more alarms to notify a user that a detected temperature is outside a predetermined range. In some embodiments, a non-linear temperature scale can be displayed.

A thermal imaging system to facilitate analysis of thermal images comprises a portable thermal imager having a communication interface for transfer of data. The imager also has an on-board memory in which image data for corresponding thermal images is stored. A remote computer is operative to communicate with the thermal imager via the communication interface for download of the image data. The computer runs software operative to superimpose at least one marker at a selected location on a thermal image, the marker being saved on the image.

System and method for analyzing thermal images

A graphical user interface for analyzing multiple thermal images is provided. The interface can be used to identify the temperatures at multiple points defined on multiple images. In some embodiments, the interface can simultaneously display temperature cursors overlaid on multiple images and provide simultaneous numerical identification of the temperatures corresponding to the area under the temperature cursors.

System and method for analyzing multiple thermal images

An infrared imaging system having functionality for maintaining image quality in the presence of temperature drift of the system. Such functionality is applied repetitively to maintain image quality of a target scene, yet without continuous actuation of a shutter of the system. The functionality of the imaging system results from implementing an imager algorithm. In use, the imager algorithm functions with a calibration curve created for the imaging system, with the curve comprising a plot of system output versus target scene temperature.

Shutterless infrared imager algorithm with drift correction

A thermal imaging system having a remote user interface comprises a portable thermal imager (such as a handheld thermal imager) having a communication interface for transfer of data. The imager further has an on-board memory in which image data is stored as well as an imager display to show a processed thermal image based on the image data stored in memory. A remote computer is operative to communicate with the thermal imager via the communication interface. The computer runs software operative to transfer the image data to the computer and show the processed thermal image on a computer display thereof on a real-time basis.

System and method for providing a remote user interface for a thermal imager

An apparatus for measuring temperature comprises a noncontact temperature measurement device situated at a first location. The device includes a sensor operative to collect radiant energy emanated from a target. Circuitry associated with the sensor produces a digital temperature signal containing temperature data regarding the target. A video camera produces a digital video signal containing video data of the target. A processor receives the digital temperature signal and the digital video signal and produces a combined digital signal for transmission to a second location. The combined digital signal contains both the temperature data and the video data. A computer situated at the second location receives the combined digital signal and separates the temperature data from the video data. Preferably, the computer includes a display having two windows on which the temperature data and the video data are respectively shown.

Noncontact temperature measurement device having compressed video image transfer

A thermal imaging apparatus comprises a thermal image camera having a lens and a display. The camera further includes a focal plane array located behind the lens for converting imaging radiation to produce an image signal for further processing. A shutter mechanism is operative to selectively inhibit exposure of the focal plane array to the imaging radiation such that the focal plane array produces a reference signal. Processing circuitry is operative to receive the image signal and produce a corresponding thermal image on the display. The processing circuitry is further operative to utilize the image signal and the reference signal to derive temperature information.
