Apparatus and method for increasing the sensitivity in the detection of optical coherence
tomography and low coherence interferometry (“LCI”) signals by detecting a parallel set of …

The ability to control the light polarization state is critically important for diverse applications
in information processing, telecommunications, and spectroscopy. Here, we propose that a …

Exemplary embodiments of apparatus, system and method can be provided to measure a
flow of fluid within an anatomical structure. For example, it is possible to use at least one first …

Polarization gratings are nondepolarizing polarization elements that alter the polarization
state of the transmitted light in a periodic way, yielding a polarization-dependent diffraction …

Optical spectroscopies are most often used to probe dynamical correlations in materials, but
they are also a probe of symmetry. Polarization anisotropies are of course sensitive to …

Exemplary embodiments of methods, arrangements and systems for obtaining information
about a sample can be provided. For example, in one exemplary embodiment, it is possible …

The concept of retardance is critically analyzed for ray paths through optical systems
described by a three-by-three polarization ray-tracing matrix. Algorithms are presented to …
