Filed:

Feb 10, 2004

Appl. No.:

10/776385

Inventors:

Thomas Heinke - Santa Cruz CA, US
Paul Carlson - Santa Cruz CA, US
Ken Pomper - Santa Cruz CA, US

Assignee:

Fluke Corporation - Everett WA

International Classification:

G01C 3/08

US Classification:

356 403

Abstract:

A radiometer includes a sighting system that generates a digital image of an object surface having an area that is to be imaged onto the IR detector. A shape outline is overlaid on the digital image of an object surface to indicate the extent of the energy zone that is imaged onto the IR detector. A rangefinder measures the distance between the radiometer and the object surface and the measured distance is utilized to determine the size of the overlaid shape.

Assignee:

Raytek Corporation - Santa Cruz CA

International Classification:

G12B 13/00

US Classification:

2502521

Abstract:

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.

International Classification:

G01B 11/14

US Classification:

356614, 356620, 374130

Abstract:

A radiometer includes a sighting system that generates a digital image of an object surface having an area that is to be imaged onto the IR detector. A shape outline is overlaid on the digital image of an object surface to indicate the extent of the energy zone that is imaged onto the IR detector. In one embodiment, a shape is displayed between the locations of two imaged skewed laser dots to indicate the extent of the energy zone without requiring a range determination.

Stefan H. Warnke - Santa Cruz CA, US

Assignee:

Raytek Corporation - Santa Cruz CA

International Classification:

H04N 7/18

US Classification:

348143, 348152, 34087007

Abstract:

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.

Assignee:

Raytek Corporation - Santa Cruz CA

International Classification:

G01J 5/06

US Classification:

374132, 374133, 374121, 2503381, 356 43

Abstract:

A thermal imaging apparatus comprises a housing defining an entrance pupil for ingress of imaging radiation. At least one light sensor is positioned forward of the entrance pupil. An electronic imaging device such as a focal plane array is located in the housing rearward of the entrance pupil for converting imaging radiation to electrical signals for further processing. The apparatus further includes a shutter having an open position and a closed position. In the closed position, the shutter is located between the entrance pupil and the electronic imaging device so as to inhibit exposure of the electronic imaging device to incident radiation. Circuitry is provided for selectively operating the shutter to be in the closed position based on signals produced at the light sensor.

International Classification:

G01J 5/00

US Classification:

250330

Abstract:

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.
