    摘要： A combined-laser-light source includes: a plurality of semiconductor lasers; an optical fiber; and an optical system which converges a bundle of laser beams emitted from the plurality of semiconductor lasers, and makes the converged bundle of the laser beams enter the core of the optical fiber so that the laser beams are combined in the optical fiber when the laser beams pass through the optical fiber. The optical system is aligned with the optical fiber so that the converged bundle of the laser beams is incident on an area of an end face of the core when steady temperature control is performed on the combined-laser-light source, where the area is concentric with the end face of the core, and has a diameter equal to or smaller than half of the diameter of the core.

    摘要： When reflection light, reflected from a measurement target that has been irradiated with measurement light in such a manner to scan the measurement target, and reference light are combined in each wavelength sweep, interference light is detected as interference signals. When a thinning region in which the interference signals obtained by detecting the interference light in each wavelength sweep are thinned so that the interference signals that are used to produce the tomographic image remain is set, thinning is performed on the plurality of interference signals in the thinning region. Light intensity information about the measurement target in the thinning region is obtained, based on the interference signals for the respective wavelength sweeps, the interference signals remaining after thinning. The tomographic image in the thinning region is produced based on the obtained light intensity information.

    摘要： Semiconductor lasers are driven such that high output laser beams are stably obtained without a long start up time. A method for driving semiconductor lasers by automatic current control or automatic power control with a constant current source involves the steps of: generating a pattern of drive current values for the semiconductor lasers, which is defined according to the amount of time which has elapsed since initiating driving thereof, that enables obtainment of substantially the same light output as a target light output by the automatic current control or the automatic power control; and varying the drive current of the semiconductor lasers in stepwise increments according to the pattern for a predetermined period of time from initiation of drive thereof. A single pattern is used in common to drive the plurality of semiconductor lasers.

    摘要： A calibration jig allowing simple and repeatable calibration of a probe optical tomographic apparatus is disclosed. The jig includes a holding member removably attachable to an attachment section of the apparatus and a reflective surface held by the holding member. The reflective surface reflects measurement light emitted from an emitting section of the attachment section and directs reflected light back to the emitting section. If a probe of the apparatus is covered with a sheath, the jig may include a light transmitting member, which generates the same dispersion as dispersion at the sheath, between the emitting section and the reflective surface. The reflective surface may be a single reflective surface disposed within an area corresponding to twice a coherence length of the laser light with a zero path position of the reflective surface being the center of the area.

    摘要： An optical tomographic imaging apparatus capable of obtaining a high resolution tomographic image rapidly. Light beams swept in wavelength intermittently and repeatedly within first and second wavelength ranges respectively are outputted simultaneously from a light source unit. If the wavelength of either one of the light beams is within a fifth wavelength range, the other light beam is not outputted. The first or second wavelength range includes at least a portion of the fifth wavelength range. Each light beam is split into measuring and reference beams by a coupler. Wavelengths of reflected beams from a measuring object when the measuring beams are irradiated on the object and the reference beams are divided by a WDM coupler. The reflected beams and reference beams are combined by an optical coupler, and each interference beam produced thereby is detected with respect to each light beam as an interference signal.
