Theory and Method

The QualiTC™ 17 handheld thermal camera detects infrared energy emitted by surfaces above absolute zero and converts that energy into a visual representation of temperature. It operates in the 8 to 14 micrometer long-wave infrared (LWIR) band using a 256 × 192 microbolometer array, providing four times the pixel count of a 120 × 90 thermal sensor. Each microbolometer responds to absorbed infrared energy by changing its electrical resistance. The camera's onboard processor analyzes these resistance changes and converts them into temperature data for individual pixels, producing a detailed false-color thermal image.

A secondary 720P visible-light camera captures a conventional image of the same inspection area alongside the thermal image. The camera system accounts for the positional difference between the thermal and visible sensors and aligns the images to provide a more accurate visual reference. Outline fusion places visible-image edges over the thermal image, while overlay fusion combines thermal and visible information at an adjustable ratio. Picture-in-picture (PIP) displays a thermal image window within the visible-light frame, giving users multiple ways to interpret thermal data within its physical surroundings.

The 5-meter distance compensation feature adjusts temperature calculations to account for changes in infrared signal as it travels through the air. This extends the correction distance beyond the 2-meter range commonly found on entry-level thermal cameras. During an inspection, high- and low-temperature tracking continuously identifies the hottest and coldest points within the viewed area.

For detailed post-inspection analysis, the companion 3D thermal analysis software can reconstruct a spatial model from captured thermal images. This provides additional insight into temperature distribution and helps users review thermal patterns after field measurements are complete.
