WebJul 3, 2007 · the Michelson interferometer. When light from the laser encounters the beam splitter it is divided in half. Half of the light is sent along path B towards the movable mirror and the other half is sent down path A towards a fixed mirror. The light then returns from each mirror and is recombined at the output and viewed on a screen. If the WebMichelson interferometry is the leading method for the direct detection of gravitational waves. This involves detecting tiny strains in space itself, affecting two long arms of the interferometer unequally, due to a strong … Webequations. We avoid a precision determination of the index by using a known vacuum wavelength and Eq. 2 to calibrate the interferometer drive screw. Neglecting the small effects of dispersion, the index then cancels from subsequent calculations.
