Correction of Errors in Polarization Based Dynamic Phase Shifting Interferometers
Polarization based interferometers for single snap-shot measurements allow single frame, quantitative phase acquisition for vibration insensitive measurements of optical surfaces and have been successfully used on a variety of interferometer types. This technique generally involves the simultaneous acquisition of three or more images on the same camera or multiple cameras, which are phase shift...
متن کاملNear-field amplitude and phase recovery using phase-shifting interferometry.
Scattering-type scanning near-field optical microscopy has allowed for investigation of light-matter interaction of a large variety of samples with excellent spatial resolution. Light incident on a metallic probe experiences an amplitude and phase change on scattering, which is dependent on optical sample properties. We implement phase-shifting interferometry to extract amplitude and phase info...
متن کاملCharacterization of the polarization sensitivity anisotropy of a near-field probe using phase measurements.
Amplitude and phase measurements of the near-field generated by isolated subwavelength apertures in a gold film are presented. The near-field distribution of such a structure is complex and the measured signal strongly depends on the electric field components effectively detected by the experimental setup. By comparing this signal with 3D vectorial calculations we are able to determine which el...

متن کاملPolarization phase-shifting point-diffraction interferometer.
A new instrument, the polarization phase-shifting point-diffraction interferometer, has been developed by use of a birefringent pinhole plate. The interferometer uses polarization to separate the test and reference beams, interfering what begin as orthogonal polarization states. The instrument is compact, simple to align, and vibration insensitive and can phase shift without moving parts or sep...
