Geometric phase interferometer
WebFringe detectors using geometric phase modulation have the potential of greatly increasing the sensitivity of optical stellar interferometers. In stellar interferometry … WebA vibration-insensitive, single-shot phase-calibration method for phase-only spatial light modulators (SLM) is reported. The proposed technique uses a geometric phase lens to form a phase-shifting radial shearing interferometer to enable common-path measurements. This configuration has several advantages: (a) unlike diffraction-based …
