How Does Stochastic Electrodynamics Influence Physical Measurements?

[ziyuang]

Hi, there.
I am not major in physics so maybe I lack some basic knowledge.
Imagine one have an ideal sensor, which can convert the emission to some kinds of signal (typically, voltage), then what process can describe the measure data? Is it related to http://en.wikipedia.org/wiki/Stochastic_electrodynamics" ?

Spontaneous electromagnetic radiation is a quantum process. Whereas stochastic electrodynamics is the effort to add some quantum concepts into classical electrodynamics without going full quantum, you could also use stochastic electrodynamics to describe spontaneous emission.

Thanks for your hint. It seems to be something called http://en.wikipedia.org/wiki/Fermi%27s_golden_rule"

Fermi's Golden Rule can be used to calculate any transition rate, not just photon emission.
