Field of view and pixel size
WebThe field-of-view (FOV) is the range of angles from which the incident radiation can be collected by the detector. The field of view may be decomposed into its horizontal and vertical components, labeled as HFOV and VFOV respectively. In both cases the FOV is determined by a combination of the focal length of the lens, f, and the size of the ... WebField of view defines the maximum area of a sample that a camera can image, determined by the focal length of the lens and the sensor size. Sensor size is determined by both …
