Field of View
The field of view (FOV) is reported as the half-angle of the apex of the cone formed by the target surface (cone base) and the
detector (cone apex), as shown below, where the target is defined as a circle from which 98 % of the radiation detected by
the radiometer is emitted.
Sensor FOV, distance to target, and sensor mounting angle in relation to the target will determine target area. Different
mounting geometries (distance and angle combinations) produce different target shapes and areas, as shown below.
A simple FOV calculator for determining target dimensions based on infrared radiometer model, mounting height, and
mounting angle, is available on the Apogee website:
