NettetIt can be stated in terms of the angle, the extent of the angle, starting from your imager out into the scene. Or it can be described as the linear extent of the scene at some distance from the imager. Instantaneous field of view, or IFOV, as we call it, is the angle subtended by just a single pixel in your detector array out into the scene.
