Latest Patents

Hamid Pahlevaninezhad holds a patent for "Systems for optical imaging of biological tissues." This invention features a fiber-based polarization sensitive optical coherence tomography (PS-OCT) system that utilizes a novel polarization diversity detection (PDD) scheme. Notably, it requires no active polarization modulating components. The system is capable of determining the retardation of the sample from the amplitudes of arbitrarily-oriented x- and y-components of the reflected light. A hybrid custom 50/50 coupler with single-mode fiber inputs and polarization maintaining (PM) fiber outputs is employed to combine light from the sample and reference arms of an interferometer. Additionally, another embodiment of the system is designed to provide co-registered autofluorescence-optical coherence tomography (AF-OCT) imaging. In this setup, AF excitation light is introduced, and the collected AF light is extracted at a fiber optic rotary joint (FORJ) equipped with an embedded dichroic mirror. A probe tip that utilizes a clad fiber to supply light to a focusing element enhances both OCT and AF performance.
