摘要： Disclosed herein are system, method, and computer-readable medium aspects for assessing ablation lesions in realtime. An aspect operates by receiving a first optical measurement data from a first catheter optical port, assigning the first optical measurement data to a first available processing core in a processing unit in order to identify an optical property at a first location of a lesion, and generating a first graphical representation from the optical property at the first location of the lesion. After a predetermined time, the aspect continues to operate by repeating the receiving, assigning, and generating operations for a second optical measurement data using a second available processing core in order to generate a second graphical representation from the optical property at a second location of the lesion. The aspect concludes by displaying the first graphical representation and the second graphical representation on a user interface at a predefined interval.

摘要： A medical instrument is described that includes an optical source, an optical fiber, and a waveguide patterned upon a substrate. The optical fiber receives radiation from the optical source and includes a first segment and a second segment. The second segment is rotated about an optical axis relative to the first segment. The waveguide receives radiation from the optical source and guides a beam of radiation. The waveguide includes a first waveguide segment designed to impart a first differential group delay on the beam of radiation and a second waveguide segment designed to impart a second differential group delay on the beam of radiation. A sum of the first differential group delay and the second differential group delay is substantially zero.

摘要： A fabrication method includes arranging a plurality of dice on a substrate and performing a first etching process that etches a first layer of the substrate at a boundary between adjacent dice on the substrate. The etching forms facets of one or more waveguides that are defined within the first layer, and the etching leaves a portion of the first layer in the boundary between the adjacent dice. The method continues with a second etching process that etches the portion of the first layer and a second layer beneath the portion of the first layer, the second etching process forming a trench in the boundary where the second layer has a different material than the first layer. The method also includes separating the dice from one another along the trench.

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： A device and a method for manufacturing the device are presented. The device includes a ridge, a peninsula formation, and a conductive trace. The ridge is defined within a semiconducting material. The peninsula formation is also defined within the semiconducting material and is adjacent to the ridge such that a gap exists between an end face of the peninsula formation and a side wall of the ridge. The conductive trace bridges across the gap such that the conductive trace runs over a top surface of the peninsula and a top surface of the ridge.

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 catheter includes proximal and distal sections, a shaft coupled between the proximal and distal sections, and optical fibers extending through the shaft and to the distal section of the catheter. The distal section includes a support structure that includes a proximal end, a distal end, reflective elements, and a cap disposed over a portion of the distal end of the support structure. The proximal end includes alignment receptacles. Each of the optical fibers is inserted into corresponding ones of the alignment receptacles and the alignment receptacles are shaped to maintain the optical fibers straight in the support structure. The distal end includes orifices facing different directions. Each of the optical fibers is optically aligned with corresponding ones of the lenses, reflective elements, and orifices such that the optical fibers in the support structure are straight. The cap includes optical ports aligned with the orifices.

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.
