WebDec 10, 2024 · This pulse can be counted or timestamped, thus giving the photon counting and time-resolved character of the camera. In a paper published in the peer-reviewed … The number of photons observed per unit time is the photon flux. The photon flux per unit area is the photon irradiance if the photons are incident on a surface, or photon exitance if the emission of photons from a broad-area source is being considered. The flux per unit solid angle is the photon intensity. The flux per unit source area per unit solid angle is photon radiance. SI units for these quantities are summarized in the table below. how can i reinstate my facebook account
