      Systems and methods for performing Gabor-domain optical coherence microscopy
      In one embodiment, imaging a medium under evaluation includes generating acquired images of the medium, each acquired image comprising a cross-sectional image along a lateral and a depth direction of the medium that results from scanning the medium at a different depths, filtering each acquired image to remove out-of-focus portions of the images and generate filtered images, and merging the filtered images to form a high-resolution fused image.

      Electronically tunable silicon photonic delay lines
      Electronically tunable optical true-time delay lines are proposed. The devices utilize the combination of apodised gratings and the free-carrier plasma effect to tune the enhanced delay of silicon waveguides at a fixed wavelength. Three variations of the proposed scheme are studied and compared. The compact and integrable devices can achieve tuning ranges as high as ~660 ps with a loss of < 2.2 dB when operated in the reflection mode ...

      Variations on the theme of quantum optical coherence tomography: a review
      Abstract  We discuss the development of quantum optical coherence tomography (Q-OCT), an imaging modality with a number of potential applications. Although Q-OCT is not expected to replace its eminently successful classical cousin, optical coherence tomography (OCT), it does offer some advantages as a biological imaging paradigm. These include greater axial resolution and higher signal-to-background ratio, immunity to dispersion that can lead to deeper subsurface penetration, and nondestructive probing of light-sensitive ...

      Methods and systems for realizing high resolution three-dimensional optical imaging
      Methods and systems for realizing high resolution three-dimensional (3-D) optical imaging using diffraction limited low resolution optical signals. Using axial shift-based signal processing via computer based computation algorithm, three sets of high resolution optical data are determined along the axial (or light beam propagation) direction using low resolution axial data. The three sets of low resolution data are generated by illuminating the 3-D object under observation along its three independent ...

      Systems and methods for generating a tunable laser beam
      Systems and methods of generating a tunable laser beam are disclosed. An example method includes: generating coherent optical beams from a plurality of semiconductor optical amplifiers (SOAs); combining the coherent optical beams into a combined coherent optical beam; and tuning the combined beam to a selected frequency range to output a coherent optical beam having only the selected frequency range. In some embodiments, the SOAs are arranged in parallel within ...

      Broadband Fourier-domain mode-locked lasers
      Abstract  Broadband, high-speed wavelength-swept lasers can substantially enhance applications in optical coherence tomography, chemical spectroscopy, and fiber-optic sensing. We report the demonstration of Fourier-domain mode-lock lasers operating at about 90 kHz effective sweep rate over a 158 nm sweep range using a single-band design and over a 284 nm sweep range across the 1.3 μm to 1.5 μm wavelength spectrum using a unique broadband design. A novel dual-detection ...

      Swept-source based, single-shot, multi-detectable velocity range Doppler optical coherence tomography
      Phase-Resolved Doppler Optical Coherence Tomography (PR-DOCT) allows visualization and characterization of the location, direction, velocity, and profile of flow activity embedded in a static sample structure. The detectable Velocity Dynamic Range (VDR) of each particular PR-DOCT system is governed by a detectable Doppler phase shift, a flow angle, and an acquisition time interval used to determine the Doppler phase shift. In general, the lower boundary of the detectable Doppler phase ...

      Liquid lens enabled optical coherence microscope with Gabor fusion
      A custom optical microscope with an integrated liquid lens to enable an extended depth imaging in biological tissue has been fabricated and shown to provide subcellular resolution using Gabor image fusion in an optical coherence tomography setup. In this paper, we report on the development and assessment path of this technology over the last few years. Specifically, we report on the optical design as well as the MTF prediction and ...

      Doppler imaging with dual-detection full-range frequency domain optical coherence tomography
      Most of full-range techniques for Frequency Domain Optical Coherence Tomography (FD-OCT) reported to date utilize the phase relation between consecutive axial lines to reconstruct a complex interference signal and hence may exhibit degradation in either mirror image suppression performance or detectable velocity dynamic range or both when monitoring a moving sample such as flow activity. We have previously reported a technique of mirror image removal by simultaneous detection of the ...
