Effective beam diameter
The beam diameter or beam width of an electromagnetic beam is the diameter along any specified line that is perpendicular to the beam axis and intersects it. Since beams typically do not have sharp edges, the diameter can be defined in many different ways. Five definitions of the beam width are in common use: D4σ, 10/90 or 20/80 knife-edge, 1/e , FWHM, and D86. The beam width can be measured in units of length at a particular plane perpendicular to the beam axis, but it ca… Websensor beam. Effective Beam Diameter Effective Beam Diameter describes the envelope of the beam which must be penetrated to operate the sensor. This is not a description of the beam projected by the sensor but rather a description of the system of emitter/receiver. The beam envelope must be penetrated by an object in order for it to be detected.
