Hello everyone,
I need to calculate the radiant power of an interference pattern of a series of light wave reflections. I need a value in Watts that would plug in nicely into a photodetector's responsivity function (given in Amps/Watts) and thus giving me an estimation of the output current.
I thought the formula would look something like this:
T is the period (all waves have the same period but are at different phases.)
E|x=0 is the superposition of all the waves (interference pattern) evaluated at x=0
To me, this formula makes the most sense, as it gives a a result in Watts.
However, my supervisor suggests that I square that value. Doesn't this give a result in Watts2?
Thank you for your help!
