A non-destructive iterative interferometric tomographic technique for imaging and reconstruction of phase objects as well as objects with complex permittivity and, particularly, to iterative optical diffraction tomographic (iODT) imaging and reconstruction of phase objects with high refractive index (RI) contrast, complex structures, and/or large optical path differences (OPDs) against the background, which cause multiple scattering, and applications thereof.

Iterative optical diffraction tomography (iODT) method and applications

A phase converting device capable of use over a broad wavelength range, which may be used for optical beam transformations and combining, conversion of resonator and waveguide modes, correction of aberrations in optical systems, and selection of photons with specific phase profile. This provides significant advantages in high power laser systems. Large-mode-area fibers can be used to provide higher incident powers than can be achieved by single-mode fibers, reducing the number of elements in a system necessary to achieve the desired output. The profiles of these LMA fiber modes can then be converted from the undesired modes into the desired mode while combing their total power into a single beam.

Achromatic holographic phase masks, methods, and applications

In one embodiment, a system and method for performing single-shot digital holography include an optical hybrid assembly configured to receive a reference beam from a light source and another beam, and a balanced detector comprising multiple sensor arrays that are configured to receive outputs of the optical hybrid assembly and simultaneously measure in-phase and quadrature components of an incoming light wavefront that results from interference between the reference beam and the other beam within the optical hybrid assembly to provide a full set of digital holograms in a single exposure.
