Summary[edit]
| Description |
English: In Optics, the concept of “etendue” is necessary to study luminance and other related quantities.
Σ: a light source with a non-zero area S: an illuminated surface dΣ, dS: corresponding differential surface elements nΣ, nS: unit vectors normal to dΣ, dS θΣ, θS: angles between nΣ, nS and the line joining dΣ, dS ΩΣ, ΩS: solid angles subtended at dΣ, dS respectively by dS, dΣEspañol: En óptica, el concepto of “extensión” es necesario para estudiar la luminancia y otras magnitudes relacionadas.
Σ: una fuente de luz con área mayor a cero S: una superficie iluminada dΣ, dS: elementos diferenciales de superficie respectivos nΣ, nS: vectores unitarios normales a dΣ, dS θΣ, θS: ángulos entre nΣ, nS y la línea recta que une dΣ, dS ΩΣ, ΩS: ángulos sólidos subtendidos en dΣ, dS respectivamente por dS, dΣ |
