The mirror has a coefficient of reflection r = 1 (it reflects all the light and does not transmit any), so we are only concerned with the half-silvered mirror. The recorded amplitude will be equal to <math> C _0 A _{laser} </math>. Because all beams that the detector will recieve will reflect off of and pass through the splitter once, we can create a new amplitude variable A such that | The mirror has a coefficient of reflection r = 1 (it reflects all the light and does not transmit any), so we are only concerned with the half-silvered mirror.
