    摘要: A system and method for triggering data acquisition in a semiconductor laser system including outputting electromagnetic energy from the semiconductor laser over a range of wavelengths according to a signaling path. The signaling path includes a plurality of discrete data inputs to the semiconductor laser for outputting electromagnetic energy over a range of wavelengths and the signaling path includes one or more perturbances in transitioning from one wavelength to another wavelength along the signaling path. A series of triggering signals for input to a measurement system is generated by the semiconductor laser. The semiconductor laser also generates a series of valid signal indicators when the outputted electromagnetic energy is not undergoing one or more perturbances. The valid signal indicators may be digitized and stored and/or used to pause the measurement system.

    摘要: A system and method for correcting the optical response of an OCT system is presented. The system and method characterize the optical response of the OCT system to determine an optical loss of the OCT system as a function of wavelength. The optical loss corresponds to a reduction in the magnitude of electromagnetic radiation leaving an interferometer of the OCT system compared to the electromagnetic radiation entering the interferometer. The optical loss of the OCT system may be determined by generating output signals using the OCT system when the system does not contain a sample or contains an electromagnetic radiation absorbing material. A controller may control the source to pre-emphasize the electromagnetic radiation to correct for the optical response of the OCT system.

    摘要: A system and method for discriminately measuring the response of a plurality of spatially separated fiber sensors positioned along an optical fiber using a sweep of electromagnetic radiation. Each fiber sensor affects the transmission of a particular wavelength of electromagnetic radiation and the particular wavelength affected by a given fiber sensor is dependent on at least one environmental property of the given fiber sensor. By detecting the particular wavelength affected by a given sensor, it is possible to determine the environmental property of the given sensor.

    摘要: A method for sweeping an electromagnetic radiation source (12) to produce single mode operation having an optimized side-mode suppression ratio over a continuous range of wavelengths within a prescribed temporal profile, the electromagnetic radiation source is configured to output electromagnetic radiation at a given wavelength based upon parameters. The method includes determining a set of parameter combinations that satisfy a condition for a desired set of wavelengths and a maximum side mode suppression ratio over the range of wavelengths. The set of parameter combinations define sub-paths for transitioning from one wavelength to another wavelength. Combinations of select sub-paths provide a multivariate path for transitioning over the range of wavelengths. The method also includes controlling the semiconductor laser to emit electromagnetic radiation over the range of wavelengths by traversing the multivariate path in a desired manner.

    摘要: A system and method including a semiconductor laser source configured to output radiation over a range of wavelengths at a prescribed rate to a device under test. The prescribed rate is sufficiently above environmental frequency bands. A detector is configured to detect output radiation from the device under test to obtain a detected signal associated with at least one physical property associated with the incident radiation over the range of wavelengths at the prescribed rate. The detected signal includes environmental signal and target signal from the device under test. A processor isolates the environmental signal from the detected signal; and processes the target signal to obtain dispersion information of the device under test. A system output is configured to output the dispersion information of the device under test.
