IFOV vs Spot Size Sun 2/20/2006
As we all know the spot size on the IR camera is not equal to the IFOV. For an accurate temperature measurement, the spot size should be at least 5 -10 times IFOV in size, right?

It depends on the camera and the type of target you are viewing. But in general for modern focal plane array cameras, your target should subtend more than 3 IFOVs.
