Definition

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

E_{p} = \frac{d Φ_{p}}{d A}

where $Φ_{p}$ is photon flux (photon flux) and $A$ is the area (ISO 80000-3: Space and time) on which the photon flux is incident

dérivée du flux photonique incident par rapport à l'aire, en un point d'une surface réelle ou fictive, exprimée par

E_{p} = \frac{d Φ_{p}}{d A}

où $Φ_{p}$ est le flux photonique (photon flux) et $A$ est l'aire (ISO 80000-3: Space and time) de la surface qui reçoit le flux photonique
