  "textContent": "The technology of a zero loop-area oblique-incidence Sagnac interferometer and methods of using the Sagnac interferometer to detect magneto-optic Kerr effect is disclosed. An example apparatus includes: a light source configured to generate an optical beam; a beam splitter; a polarizer configured to separate the optical beam into two orthogonal components; a modulator configured to phase-modulating at least one of the two orthogonal components to produce a modulated pair of orthogonal components; a polarization dependent delay optics configured to direct the modulated pair of orthogonal components toward a surface of a sample to cause the modulated pair of orthogonal components to incident on the surface at an oblique angle; a mirror configured to reflecting the modulated pair of orthogonal components back towards the beam splitter; a photo receiver configured to receive a return beam redirected by the beam splitter; and a phase-sensitive detector.",
