IR-Fusion is thermal imaging technology patented by the Fluke Corporation that automatically captures a digital visible light image at the same time as an infrared image. The camera blends the two images together, pixel for pixel, in a single display. Technicians can then view the image in full infrared, full visible light or at several degrees of blending in between. IR-Fusion technology is available in many Fluke infrared cameras and in Fluke SmartView® software.
Because the infrared and visible images are matched pixel for pixel, the operator can easily identify the location of infrared points-of-interest on the target by noting where the features are in the blended image. The location of an infrared target can be precisely identified even if the infrared contrast is low and there is very little structure in the infrared image.
IR-Fusion display features
IR-Fusion offers several display modes to further help isolate problem areas. Temperatures are recorded in all of these modes and can be displayed in the infrared portion of the image. IR-Fusion display modes include:
- Picture-in-picture mode. The center quarter of the display is infrared-only, visible-only, or a blend of the two. The remaining three quarters of the screen is visible only.
- Full screen. The center quarter of the picture-in-picture mode fills the screen. As in picture-in-picture mode, that full screen image can be visible-only, infrared-only, or a blend of the two.
- Color alarm mode. This mode highlights areas of interest that exceed user-set high and low temperature levels. Choose from three settings:
- Hot threshold: Any pixel in the image with a temperature above a temperature setting will appear in infrared colors.
- Cold threshold: Any pixel in the image with a temperature below a temperature setting will appear in infrared colors.
- Absolute range (isotherm): When the camera operator specifies both an upper and lower temperature threshold, any pixel with a temperature outside of this range will appear in infrared colors.
In all color-alarm modes, the colors are set by the infrared palette selection and the intensity is set by the degree of infrared blending. You can set the mode display as either picture-in-picture or full-screen.
With Fluke SmartView software IR-Fusion images can be optimized and used in reports and presentations to add impact.
