Definition

density of incident radiant energy with respect to area at a point on a real or imaginary surface, expressed by

H_{e} = \frac{d Q_{e}}{d A}

where $Q_{e}$ is radiant energy (radiant energy <electromagnetism>) and $A$ is the area on which the radiant energy is incident (ISO 80000-3: Space and time)

dérivée de l'énergie rayonnante incidente par rapport à l'aire, en un point d'une surface réelle ou fictive, exprimée par

H_{e} = \frac{d Q_{e}}{d A}

où $Q_{e}$ est l'énergie rayonnante (radiant energy <electromagnetism>) et $A$ est l'aire (ISO 80000-3: Space and time) de la surface qui reçoit l'énergie rayonnante

Notes

The corresponding photometric quantity is "luminous exposure" (luminous exposure). The corresponding quantity for photons is "photon exposure" (photon exposure).

La grandeur photométrique correspondante est l'«exposition lumineuse» (luminous exposure). La grandeur photonique correspondante est l'«exposition photonique» (photon exposure).
