Term:

Radiometry

Explanation: the science of quantifying the phenomena of electromagnetic radiation.

In our context, we are only interested in the limited range of electromagnetic radiation that is visible to the human eye, sometimes extended to the areas of infrared and ultraviolet. We also don't care about the quantum mechanical aspects of radiation. It will be enough to measure the physiologically perceiveable effects.
