Radiometric Temperatures

We’ve spent the past several weeks discussing heat transfer. Radiation is a special mode of transfer because that is the mode by which energy is transferred from surfaces to our imagers.

All of what we see in the thermal image is nearly always based on the amount of radiation emitted from or reflected by the surface. […]

Emissivity: Understanding How it Affects Your Thermal Images

I often joke that were it not for emissivity, you’d not need training to use an imager! In our courses we find emissivity is the #1 most confusing issue for people, whether they are engineers, home inspectors or new thermographers. In fact, we all usually have a good laugh that many cannot even pronounce the […]
