    Abstract: 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 spectral bands, each band being a unique combination of optical frequencies. The LCI broad bandwidth source is split into N spectral bands. The N spectral bands are individually detected and processed to provide an increase in the signal-to-noise ratio by a factor of N. Each spectral band is detected by a separate photo detector and amplified. For each spectral band the signal is band pass filtered around the signal band by analog electronics and digitized, or, alternatively, the signal may be digitized and band pass filtered in software. As a consequence, the shot noise contribution to the signal is reduced by a factor equal to the number of spectral bands. The signal remains the same. The reduction of the shot noise increases the dynamic range and sensitivity of the system.

    Abstract: Optical coherence tomography (OCT) is an imaging method which can image with micrometer-scale resolution up to a few millimeters deep into, for example, living biological tissues and preserved tissue samples. An improved apparatus and image reconstruction algorithm for parallel Fourier Domain OCT which greatly eases requirements for interferometer stability and also allows for more efficient parallel image acquisition is provided. The apparatuses and algorithms reconstruct images from interfered, low-coherence, multiwave length signals having a π radian phase difference relative to one another. Other numbers of signals and other phase differences may be alternatively used, with some combinations resulting in higher resolution and image stability. The apparatus also eliminates a need for bulk optics to modulate a phase delay in a reference arm of the optical path. Images may be reconstructed using two spectrometers, where each is coupled to a detector array such as a photodiode array.

    Abstract: OCT apparatus includes an interferometer, having an input beam splitter and a 50/50 output splitter. The splitting ratio of the input splitter may be optimized depending on the source power of light source and on the mismatch of the balanced receiver. The input splitter is a plate beam-splitter to minimize the stray reflected light in the interferometer and allow sequential operation of the apparatus in the OCT or in the confocal regime. The switching between the two regimes may be at will, or synchronous with the en-face scanning which results in quasi-simultaneous OCT/confocal imaging or in alternatives frames, confocal and OCT. By using polarization sensitive elements, two channels are provided in each regime, OCT and confocal. The two confocal polarization sensitive channels may allow adjustments of compensators prior to OCT measurements or OCT imaging.

    Abstract: The invention provides an interferometric system and method for quadrature detection of optical characteristics of a sample. The system includes a Mach-Zehnder interferometer providing a variable optical delay between light collected from the sample and reference light. The Mach-Zehnder interferometer has an output M×N coupler with N≧3 output ports. Two differential detectors, each having two input ports coupled to a different two of the N output ports of the M×N coupler, produce first and second electrical signals having an interferometric phase shift. A processor is provided for computing real and imaginary parts of a complex refractive index of the sample from the first and second electrical signals by using complex deconvolution.

    Abstract: Optical coherence tomography with 3D coherence scanning is disclosed, using at least three fibers (201, 202, 203) for object illumination and collection of backscattered light. Fiber tips (1, 2, 3) are located in a fiber tip plane (71) normal to the optical axis (72). Light beams emerging from the fibers overlap at an object (122) plane, a subset of intersections of the beams with the plane defining field of view (266) of the optical coherence tomography apparatus. Interference of light emitted and collected by the fibers creates a 3D fringe pattern. The 3D fringe pattern is scanned dynamically over the object by phase shift delays (102, 104) controlled remotely, near ends of the fibers opposite the tips of the fibers, and combined with light modulation. The dynamic fringe pattern is backscattered by the object, transmitted to a light processing system (108) such as a photo detector, and produces an AC signal on the output of the light processing system (108). Phase demodulation of the AC signal at selected frequencies and signal processing produce a measurement of a 3D profile of the object.

    Abstract: A system for tomographic imaging includes a source of at least partially coherent radiation, a frequency-swept laser source and an interferometer. The radiation in the interferometer is phase modulated at a modulation frequency for elimination of DC and autocorrelation noises as well as the mirror image. The interference fringes of the radiation backscattered from the sample into the interferometer are detected to obtain a spectral signal. The spectral signal of the detected backscattered interference fringes is transformed to obtain a location dependent signal at each pixel location in a data window. A tomographic image of the fluid flow in the data window is generated for display and of the structure of the scanned fluid flow sample in the data window from the location dependent signal is generated.

    Abstract: Disclosed are compact optical interferometer array, miniature optical interferometer array, and miniature optical interferometer. The interferometer arrays contain a spatial phase modulator array and a detector array. They are used for conducting multiple measurements. The miniature interferometer has only one component—a spatial phase modulator. Without passing through any focus lens, beam portions coming out of the modulator spread and merge together by themselves. Size of the miniature interferometer can reach subwavelength or even nanoscale. The interferometer array and miniature interferometer find applications in miniature spectrometer, color filter, display, adjustable subwavelength grating, etc.
