We refer to this observable area as the field of view (FOV). Understanding the size of the FOV is important because actual sizes of the object can be calculated using the Magnification of the lenses.

Nettet11. mai 2024 · How to calculate the instantaneous field of view? Instantaneous field of view or (IFOV) is an important calculation in determining how much a single detector pixel can see in terms of field of view (FOV). To determine the IFOV, please use one of these two common methods below. Method 1: IFOV=Detector Element Size/Camera Focal … NettetSpatial resolution is a measure of the smallest object that can be resolved by the sensor, or the ground area imaged for the instantaneous field of view (IFOV) of the sensor, or the linear dimension on the ground represented by each pixel.
