WebIn photography, angle of view(AOV)[3]describes the angularextent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view. It is important to distinguish the angle of view from the angle of coverage, which describes the angle range that a lens can image. WebThe f/# of the lens controls how quickly the cone expands and how much information or detail is blurred together at a given distance. Figure 3a shows a lens with a shallow DOF, where Figure 3b shows a lens with a large DOF. Figure 3: Geometric representation of DOF for high and low f/# lenses. dut accreditation

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 ... WebField of View (FOV): The viewable area of the object under inspection. This is the portion of the object that fills the camera’s sensor. Only the horizontal field of view needs to be entered as the vertical and diagonal will be calculated automatically based on the aspect ratio of the sensor size previously entered.
