摘要： A free-space Michelson Interferometer-based Dual Detection Frequency Domain-Optical Coherency Tomography (DD-FD-OCT) apparatus includes a non-polarizing beam splitter that can be used to misalign sample and reference beam paths to provide a stable π/2 phase shift between simultaneously detected interfering sample and reference beams to eliminate the mirror image created by Fourier transformation during image reconstruction. A hybrid fiber system Mach Zehnder Interferometer- and free-space Michelson Interferometer-based Dual Detection Frequency Domain-Doppler Optical Coherency Tomography (DD-FD-DOCT) apparatus provides higher power efficiency and thus better sensitivity compared to the free-space DD-FD-OCT. Both DD-FD-OCT systems enable functional imaging with the contrasts of Doppler and that of polarization, in addition to full range images simultaneously.

摘要： An optical coherence tomography(OCT) and spectral interferometry imaging probe for the automatic screening and diagnosis of cervical and skin cancer in vivo. The probe eliminates the old techniques of having to perform Pap smears followed by a biopsy, known as colposcopy. The novel probe is cylindrical in shape and has a disposable outer plastic shield. Inside the probe is a motor driven rotatable casing having a planar optical fiber bundle array therein. The fiber bundle array has plastic light coupling lenslet arrays on both ends. The exposed end of the probe has one lenslet array disc that couples light between the probe and an interior of the cervix area being examined. Both the casing and the bundle array rotate relative to the outer probe walls. Inside the casing is a rotatable motor driven scanning mirror which couples passes light from an incoming second fiber bundle array to the lenslet array on the inside end of the rotatable casing fiber bundle array. The incoming second fiber bundle array is attached to a detector located external and remote to the probe. The detector has a tunable light source and a spectrometer for providing 3-D images of the interior of the cervix. The proposed technique of simultaneous OCT imaging and spectral interferometry and analysis has potential use in either multi-layer optical disk read out using low coherence tomography and spectral interferometry. Alternatively, by employing spectral interferometry, the measured optical spectrum also provides a unique mapping of the recorded bits into the observed spectral modulation. The unique feature is that by simultaneously employing both spectral interferometry and low coherence tomography, the resultant data transfer rate is increased, but the combination also allows for error rate analysis.

摘要： A device for conforming photodynamic therapy to a specific anatomic location (e.g., in the oral cavity) conforms the radiation to the target tissue surface and avoids delivering light to the rest of the oral cavity. Embodiments can include a body of oral impression material molded to conform to the anatomic surface, a light pipe, a freeform reflector formed on a surface of the optical body, or a light guide having a textured surface to direct light to an opposing output window. The light guide can be made of flexible plastic to conform the output window to the lesion.
