Field angle optics
In the context of human and primate vision, the term "field of view" is typically only used in the sense of a restriction to what is visible by external apparatus, like when wearing spectacles or virtual reality goggles. Note that eye movements are allowed in the definition but do not change the field of view when understood this way. If the analogy of the eye's retina working as a sensor is drawn upon, the corresponding concep… WebFor a diffraction-limited Gaussian beam, the 1/e 2 beam divergence half-angle is λ / (π w 0), where λ is the wavelength (in the medium) and w 0 the beam radius at the beam waist.This equation is based on the paraxial …
