摘要： A Time Domain Optical Coherence Tomography system using a modulation scheme multiplexes the scanning range of the delay line into different spectral bands. Such a modulation scheme may allow for power consumption reduction compared with a single delay line element since the same modulation pattern is being used for several channels. In an example, the optical coherence tomography system may include a plurality of stages, each stage having a group delay element. The distinct group delays may be introduced to scan a sample with distinct electrical frequency bands at distinct axial scanning depth ranges.

摘要： Systems and methods for performing RF ablation while monitoring the procedure using low coherence interferometry (LCI) data are described. A catheter includes a distal section, a proximal section, a multiplexer, and a sheath coupled between the distal section and the proximal section. The distal section includes several interconnected optical ports configured to transmit exposure radiation toward a sample and receive radiation that have been reflected or scattered from the sample. The interconnected optical ports are formed on a substrate having rigid sections and flexible sections arranged around the distal section. A holder maintains the interconnected optical elements in a fixed spatial relationship.

摘要： A system for optical coherence tomography using multiple interferometers presented. The interferometry system includes a source configured to generate a variable wavelength light beam. A first splitter is configured to split the variable wavelength light beam to at least a first light beam and a second light beam. A first delay element is configured to delay the first light beam by a first time delay. A second delay element is configured to delay the second light beam by a second time delay, such that the delayed first light beam and the delayed second light beam are out of coherence with each other. A first interferometer is configured to receive the delayed first light beam as an input. A second interferometer is configured to receive the delayed second light beam as an input.

摘要： A scanning device is presented having a substrate with a first surface and an opposite, parallel second surface. A region of the substrate includes the first surface and the opposite parallel second surface, and is defined via an etching process through a thickness of the substrate, where the region remains attached to the substrate via one or more hinges. A waveguide is patterned over the first surface of the region and guides a beam of radiation along a length of the waveguide. The scanning device includes a facet located on the first surface of the region. The facet is designed to reflect at least a portion of the beam of radiation through the region. An optical element is located on the second surface of the region, and is designed to receive the reflected portion of the beam of radiation.

摘要： Systems and methods are presented for modulating a beam of radiation, such that the modulated beam exhibits substantially null residual amplitude modulation (RAM). An electro-optical modulator is presented that includes a waveguide, a first region associated with the waveguide and a second region associated with the waveguide. The waveguide is designed to guide a beam of radiation. A first electric potential applied to the first region causes a first modulation to the beam of radiation while a second electric potential applied to the second region causes a second modulation to the beam of radiation. The first modulation combined with the second modulation provides substantially null residual amplitude modulation of the beam of radiation.

摘要： A photonic integrated circuit is presented that includes a substrate, and a first and second waveguide patterned on the substrate. The first waveguide guides an input beam of radiation. The photonic integrated circuit also includes a coupling region, wherein the first and second waveguides each pass through the coupling region. One or more modulating elements are coupled to each of the first and second waveguides. The first waveguide and the second waveguide have a first facet and a second facet, respectively, and first and second reflections are generated at the first and second facets within the first and second waveguides, respectively. The one or more modulating elements coupled to each of the first and second waveguides are designed to adjust the phase of the first and second reflections before the first and second reflections pass through the coupling region.
