  • Publication number: 20190175023
    Abstract: Embodiments for crossing an occlusion by controlling a guide with the aid of optical coherence tomography (OCT) data are described. Embodiments include transmitting one or more beams of radiation via one or more waveguides on a flexible substrate within a guide wire. One or more beams of scattered or reflected radiation may be received from a sample via one or more waveguides. Depth-resolved optical data of the sample may be generated based on the received beams of scattered or reflected radiation. The depth-resolved data may be used for determining at least one of a distance between the guide wire and a wall of the artery and a distance between the guide wire and an occlusion within the artery. A position of the guide wire within the artery may then be controlled based on the determined distance or distances.

  • Patent number: 10113858
    Abstract: 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.

  • Patent number: 9310185
    Abstract: 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.
