WebSince angular FOV is independent of object distance, it is the more frequently used form of FOV. For an imaging sensor (or film) of size a in a given direction, the angular FOV in that direction is 2 arctan (a / 2 s i). When the system is set to focus at optical infinity, this takes on the familiar form of 2 arctan (a / 2 f). The shape of the ... WebJun 1, 2024 · Unique optical parameters that enable imaging systems to capture the full visible FOV include the lens aperture position and geometry. In an optical system, such as the lens on a camera, the aperture or “entrance pupil” is the initial plane where light is received into the lens. A similar point exists in the pupil of the human eye.
