Director’s Message

Resolution is one of the most important objective specifications for any thermal imaging system. Pixel count is frequently offered as a measure of image quality; however, pixel count is only one of many factors that affect imager resolution.

The Focal Plane Array (FPA) detector assemblies used in modern infrared imagers contain thousands of tiny, discrete picture elements or pixels. Each pixel is a separate infrared detector that collects thermal data. Individual pixels are arranged to form an array that ultimately allows the imager to produce a thermal image.

FPA detectors are commonly specified according to pixel count and ratio. Typical detector sizes for industrial imagers range from 160W by 120H to 320W by 240H; some detectors may have more or less pixels. To determine the total pixel count for a detector; the horizontal and vertical values are multiplied.

Imager manufacturers often cite pixel count as a measure of imager resolution. Imager sales are won and lost as entire advertising campaigns focus heavily on this single objective specification. Actually determining resolution is not that simple.

Although resolution generally increases with the number of pixels, there are several other factors that influence image clarity or resolution. These include, but are not limited to, pixel viewing angle, imager optics, signal-to-noise ratio, and the imager’s display screen.

When evaluating an imager for resolution, it is best to physically try the imager under actual working conditions. Imagers that produce clear images should be sufficient for qualitative imaging regardless of pixel count.


Level I Courses Expand Across Asia Pacific Region

Beginning August 31, the Infraspection Institute Level I Certified Infrared Thermographer® course will be available in Singapore, Thailand, Malaysia, Philippines, Vietnam, New Zealand, and Fiji. These courses will be hosted by IPI Learning, headquartered in Melbourne, Australia.

Compliant with ISO and ASNT requirements, Level I Certified Infrared Thermographer® is a five-day course for the application of qualitative thermal imaging for P/PM, Condition Assessment, Condition Monitoring, Quality Assurance, Forensic Investigations, and Building Sciences. Taught by highly-experienced Level III certified thermographers, this course covers infrared theory, heat transfer concepts, equipment operation and selection, standards compliance, image analysis, and report generation.

Students are trained to identify and document thermal patterns caused by improper design, workmanship or material failure.  Specific applications include: electrical distribution systems, mechanical systems, steam systems, refractory systems, underground piping, active thermography, building envelopes, and flat roofs.
