  • Radiometry: A Simplified Description of Light

    The intensity of the incident light can be a function of time. It is a “DC light” if the intensity is constant, “AC light” if the intensity varies with time, and “pulsed light” if it arrives as discrete packets of photons. DC light poses no additional restrictions on the photodetector, whereas the other two do impose restrictions.
