Light phase shift in the field of a gravitational wave

  • P. Fortini
  • A. Ortolan
Note Brevi


We show that the response of an interferometric device to a monochromatic gravitational wave results from two different contributions: one due to the change of space geometry (mirror motion) and the other one due to the change of time rate (photon red- or blue-shift). An alternative exact derivation of phase shift is given.
