measure of a conical geometric figure, called solid angle, formed by all rays, originating from a common point, called the vertex of the solid angle, and passing through the points of a closed, non-self-intersecting curve in space considered as the border of a surface
grandeur associée à une figure géométrique conique, appelée aussi «angle solide», formée par toutes les demi-droites ayant pour origine le même point, appelé sommet de l'angle solide, et passant par les points d'une courbe fermée de l'espace ne se recoupant pas et considérée comme le bord d'une surface
Notes
The differential solid angular measure expressed in spherical coordinates (ISO 80000-2: Mathematics) is given by:
where is area, is radius, and are spherical coordinates.
La mesure différentielle d'angle solide, exprimée en coordonnées sphériques (ISO 80000-2: Mathematics), est donnée par:
où est l'aire, est le rayon, et sont les coordonnées sphériques.
