Photometry: The Answer to How Light Is Perceived - Photonics

Photometry is the science of the measurement of light, in terms of its perceived brightness to the human eye. It is distinct from radiometry, which is the science of measurement of radiant energy (including light) in terms of absolute power. In modern photometry, the radiant power at each wavelength is weighted by a luminosity function that models human brightness sensitivity. Typically, this we… WebA ‘light meter’ is a handheld device that used measure or ‘meter’ light.
