    Abstract: A channel detection system includes an interferometer coupled to a spectrum analyzer to differentiate additive spontaneous emission (ASE) noise from optical channels in a dense wave-division multiplex (DWDM) signal. It is assumed that channels, if present, are centered at frequencies corresponding to a standardized channel grid. The relative delay of the interferometer is chosen to be greater than the coherence time of the ASE noise but less than the coherence time of the channels with the interferometer's free spectral range set to an integer divisor of the channel-to-channel frequency spacing of the grid such that active channels experience a high degree of interference. The phase delay of the interferometer is then adjusted to maximize the interference at each grid-aligned frequency. The spectrum-analyzed outputs are compared (e.g., subtracted from one another and then thresholded) to determine the channels present in the DWDM signal.

    Abstract: A flexible shaft driven to rotate is inserted through a transparent sheath having pliability. By a fiber inserted through the inside thereof, low-coherence light is guided and is made to exit to a living-body tissue side which is an observation target through a lens and a prism forming an exit and entrance portion at the tip portion. Subsequently, the light reflected on the living-body tissue side is guided in order to produce an image. In that case, a positioning member for keeping the exit and entrance portion and the living-body tissue at a proper distance is formed at the tip portion of the sheath or the tip portion of an endoscope through which an optical probe is inserted and, therefore, a stable tomogram image can be produced.

    Abstract: An improved method and apparatus for controlling a scanning laser are provided by the present invention. In accordance with a preferred embodiment, a single feedback sensor is placed along the scan path of a scanning laser such that it senses the laser twice during each scan. The time intervals between the sensor sensing the laser are measured and examined to determine the position and direction of the scanning laser. These time intervals may also be used to ensure that the scanning device is operating at its resonant frequency. In systems that require detecting the laser as it enters and leaves the imaging window, a reflective device is used to create a beam path from the edge of the imaging window back to the single feedback sensor such that the sensor detects the laser four times during each scan. In such an embodiment, the drive signal used to scan the laser along its scan path can be compared to the pulses received from the sensor to determine whether or not a detected time interval corresponds to a particular physical portion of the scan path.

    Abstract: A laser machining apparatus machines a workpiece at uniform intensity by converting a CO2 laser beam to uniform intensity using an intensity-converting element and a phase-matching element. The optical transmission system is configured such that the starting point of the laser beam pointing vector and the exit face of the intensity-converting element are mutually conjugated with respect to the optical transmission system. This structure offers stable machining by ensuring that the laser beam always enters the intensity-converting element at its center, even if the pointing vector of the laser beam shifts.

    Abstract: High quality images are provided without the occurrence of image quality defects due to reciprocity law failures, even when scanning a multi-beam. When interlaced scanning is employed, it is possible to select combinations such that, taking any freely selected neighboring scanning lines, respective scan numbers of the neighboring scanning lines are always different. Thus, a duration of scanning spacing can be made to be at least the duration of a single main scan. As a result, image defects such as banding due to reciprocity law failures can be greatly alleviated, and images can be provided in which image defects are to unlikely to be noticed in practice.
