| Radiometry: Radiance definition geometry | Parent topic |
Fig. 1. Geometry of the radiance definition: dΦ - radiant flux which propagates within an elementary solid angle, dω, about the direction of observation, ξ; dA - elementary area of the radiation source with its normal, n; dAp = dA cosθ - projection of the elementary area onto a plane perpendicular to the direction of observation, ξ.
