Conjugate adaptive optics in widefield microscopy with an extended-source wavefront sensor
Jiang Li, Devin R. Beaulieu, Hari Paudel +3
Adaptive optics is a strategy to compensate for sample-induced aberrations in microscopy applications. Generally, it requires the presence of "guide stars" in the sample to serve a…
High-resolution 3D phase imaging using a partitioned detection aperture: a wave-optic analysis
Roman Barankov, Jean-Charles Baritaux, Jerome Mertz
Quantitative phase imaging has become a topic of considerable interest in the microscopy community. We have recently described one such technique based on the use of a partitioned…
High-throughput Imaging of Self-luminous Objects through a Single Optical Fiber
Roman Barankov, Jerome Mertz
Imaging through a single optical fiber offers attractive possibilities in many applications such as microendoscopy or remote sensing. However, the direct transmission of an image t…
Single-exposure profilometry using partitioned aperture wavefront imaging
Roman Barankov, Jerome Mertz
We demonstrate a technique for instantaneous measurements of surface topography based on the combination of a partitioned aperture wavefront imager with a standard lamp-based refle…
Cross-correlation Imaging for Waveguide Characterization
R. A. Barankov
Confined geometries, such as optical waveguides, support a discrete set of eigen-modes. In multimoded structures, depending on the boundary conditions, superposition states can pro…
Quench dynamics as a probe of quantum criticality
R. A. Barankov
Quantum critical points of many-body systems can be characterized by studying response of the ground-state wave function to the change of the external parameter, encoded in the gro…
