This image comparison shows how the diffrent FOVs influence the image frame of the

individuall camera:

In the first comparison all thermal imagers measure an object from the same distance. So you

can see the different image sections you get with several FOV’s of the thermal imagers.

In the second comparison we tried to get the same image section for every thermal imager

with the different FOV’s. So the objects had to be measured from different distances,

depending on the camera. You will see these different distances in the presentation.
