Detector solid angle
WebSolid angle is a three-dimensional analog of an included angle in a two-dimensional plane. Shown in Fig.1, an arbitrary solid angle can be de ned by the area Ait would cover on a sphere of radius Rcentered at the apex of the solid angle. = A R2 (5) Solid angles are expressed in the dimension-less units of steradian, abbreviated sr.1 One
