D:S* = Distance to Spot = {{camera.DtoS | number:0}}:1
IFOV = Instantaneous Field of View
*Note: All calculations are approximate. D:S theoretical (= 1/IFOV theoretical) is the calculated spot size based on the pitch of the camera detector array and lens focal length. D:S measured (= 1/IFOVmeasured) is the spot size needed to provide a more accurate apparent temperature calculation. Typically, D:S measured is 2 to 3 times smaller than D:S theoretical, which means the temperature measurement area of the target needs to be 2 to 3 times larger than that determined by the calculated theoretical D:S. © 2005-2015 Fluke Corporation.
