I’m a firefighter and we just bought new TICs (Thermal Imaging Cameras). We did a training to familiarize ourselves with the new equipment and simulated searching for people in the station gym. While using it, I noticed that the display would show a silhouette of my body in the mirror. The way these cameras work (as I understand it) is not to look for an image to repeat on a screen, but to look for heat. I understand that my body gives off heat, and that’s how it distinguishes people for the image. However, the “me” in the mirror isn’t me. It’s only a reflection. So, shouldn’t the camera just show no heat coming off the wall/mirror?
In: Technology
heat is just light you cant normally see. mirrors can reflect it fine.
This is why heat resistant suits (for like foundry work) are shiny. and why reflective foil can help cook things.
This is alao how mylar emergency blankets work
