Incoming radiance
WebWe present a theoretical analysis of the relationship between incoming radiance and irradiance. Specifically, we address the question of whether it is possible to compute the … WebNov 19, 2014 · While irradiance refers to incoming power, the radiance is used for two cases: angle-dependent diffuse reflection ( BRDF) emission from light sources. E.g. radiance in direction of the optical axis of a LED is higher, than its radiance at an angle of 15°. Optical simulations / ray tracing calculate the irradiance on surfaces.
