RE: Temperature measurement in an inaccessible location [camera FLIR] ?
Well i'm not an expert in infrared thermography, but a lot of sources i've read / speak with told me that emissivity varies with the viewing angle, but that after 25/30° to the perpendicular, it totally drop and it was nonsense..
And my camera would be atleast at 50° to the normal of the surface, so i'm searching for answers..

Plus since my camera would observe with a wide angle, the "bottom" of the image would be closer to the camera then the "background" of the image, so i think with the field depth that would be a problem
