Detection of Interference Phase by Digital Computation of Quadrature Signals in Homodyne Laser Interferometry

Detection of Interference Phase by Digital Computation of Quadrature Signals in Homodyne Laser Interferometry

We have proposed an approach to the interference phase extraction in the homodyne laser interferometry. The method employs a series of computational steps to reconstruct the signals for quadrature detection from an interference signal from a non-polarising interferometer sampled by a simple photodet...
