    摘要： Disclosed herein are optical integration technologies, designs, systems and methods directed toward Optical Coherence Tomography (OCT) and other interferometric optical sensor, ranging, and imaging systems wherein such systems, methods and structures employ tunable optical sources, coherent detection and other structures on a single or multichip monolithic integration. In contrast to contemporary, prior-art OCT systems and structures that employ simple, miniature optical bench technology using small optical components positioned on a substrate, systems and methods according to the present disclosure employ one or more photonic integrated circuits (PICs), use swept-source techniques, and employ a widely tunable optical source(s).In another embodiment the system uses an optical photonic phased array. The phase array can be a static phased array to eliminate or augment the lens that couples light to and from a sample of interest or can be static and use a spectrally dispersive antenna and a tunable source to perform angular sweeping. The phased array can be active in 1 or 2 dimensions so as to scan the light beam in angle. The phased array can also adjust focus. The phased array can implement an optical waveform that will extend depth of field focus for imaging. The phase array can also be a separate standalone element that is fed by one or more optical fibers. The phased array can be for scanning a biomedical specimen used in conjunction with a swept-source OCT system, can be used in a free-space coherent optical communication system for beam pointing or tracking, used in LIDAR applications, or many other beam control or beam steering applications

    摘要： An enhanced transfer system that increases the accuracy and sensitivity of a measurement system is disclosed. In one embodiment, the transfer system includes transfer tubing that transports samples from a spray chamber to an ionizer in a mass spectrometer system. The transfer system also includes a transfer gas line that is connected to the transfer tubing. The transfer gas line supplies a gas that assists with the transferring of the samples from the spray chamber to the ionizer. In one embodiment, the transfer gas line is angled relative to a portion of the transfer tubing. In another embodiment, the transfer gas line is perpendicular relative to a portion of the transfer tubing. The injected gas increases the quantity and quality of the samples transferred to the mass spectrometry system, thereby increasing the overall accuracy and sensitivity of the measurement system.

    摘要： An improved control method that constrains the operation of a manipulator in a control system is provided. Modifying a conventional control system to conform to this new method requires the selection of a preferred or desired direction of adjustment for the manipulator and the selection of a reset value for the manipulator. The conventional control system, which normally adjusts the manipulator as necessary to achieve a desired value for a system variable, is constrained by this new method so that the system variable achieves the desired value as a final or direct result of using manipulator adjustments that are in the selected desired direction of adjustment.

    摘要： An optical probe imaging system includes an optical probe with a multicore optical fiber positioned therein. Distal optics are optically coupled to the distal end of the multicore fiber that image light propagating in the multicore fiber so as to generate a light pattern on a sample that is based on a relative position of at least two cores at a distal facet of the multicore fiber. A distal motor is mechanically coupled to the optical probe so that a motion of the distal motor causes the light pattern to traverse a path across the sample. An optical receiver is coupled to the proximal end of the multicore fiber and receives light that has traversed the path across the sample and then generates an electrical signal corresponding to the received light. A processor maps the electrical signal to a representation of information about the sample, wherein the mapping is based on the relative position of at least two cores at the distal facet of the multicore fiber and on the motion of the distal motor.
