Thermal Imaging Camera

Over the weekend I had a chance to borrow a thermal imaging camera.

Thermal imaging works by using a special lens which focuses the infrared light emitted by all of the objects in view.
The focused light is scanned by infrared-detector elements. The detector elements then create a detailed temperature pattern called a thermogram.
The thermogram is translated into electric impulses. The impulses are sent to a signal-processing unit, which turn it into data for the display, where it appears as various colours depending on the intensity of the infrared emission. The combination of all the impulses from all of the elements creates the image.

It takes a while to get used to the temperature scale to get the best picture.

I took the thermal imaging camera out during the day. It is a lot harder to make things out at a distance, but I like the way you can take a photograph as well as the thermal image.

The most interesting image is of the oak tree covered in Ivy as you can see how much hotter the Ivy is than the tree trunk.


Here on my dog, the white parts are the warmest. The red areas such as his tail and the tips of his ears are slightly cooler.

Later that evening we watched two badgers on the edge of woodland, without the thermal imaging camera we could only hear them.

You can just make out the small blue dot which is a Fox running across the field.

I presume this is two badgers but can’t say for sure.

This glowing white blob is a Wood Mouse, which I spotted in the torchlight.

I think this one is a Rabbit.


This is what a Human looks like on a thermal imaging camera.

    Wow! I’ve always wanted to try a thermal camera. They look brilliant

  2. Really impressive. I have tried out infrared sights on my latest blog with similar effect but you cant beat thermal for picking out unseen stuff.

    Fascinating stuff. The effect of the ivy growing up the tree trunk is interesting – a definite warm home for somebody, I’m sure. What make and model of thermal camera were you using?
