摘要： An optical probe includes a tubular outer envelope and a optical fiber which extends in the longitudinal direction of the outer envelope inside the outer envelope. By fixing a light deflecting element to the optical fiber and rotating the optical fiber by a driver, the light deflecting element is rotated. A protective member which has a higher resistance to wear than the outer peripheral surface of the optical fiber is fixed to a part of the outer peripheral surface of the optical fiber in a position near the front end of the optical fiber and is borne for rotation by a bearing portion on the probe outer envelope.

摘要： A polarization maintaining optical fiber, for guiding a measuring light beam, is provided within a probe. The probe is configured to be rotatable in the circumferential direction of the polarization maintaining optical fiber. A polarization direction rotator, for rotating the polarization direction of the measuring light beam that enters the polarization maintaining optical fiber accompanying rotation of the probe, is provided in order to maintain a state in which the polarization direction of the measuring light beam that enters the polarization maintaining optical fiber and the direction of the polarization axis of the polarization maintaining optical fiber are matched.

摘要： Light emitted from the light source unit is divided into measuring light and reference light. An optical path length of the measuring light or the reference light which has been divided by the light dividing means is adjusted. Interference light of the reflected light and the reference light is detected and a tomographic image of the object is obtained on the basis of the detected interference light. The optical path length is adjusted by a reflecting mirror which reflects the measuring light or the reference light radiated from the optical fiber, a first lens which is disposed between the reflecting mirror and the optical fiber and a second lens which collects the measuring light or the reference light made parallel by the first lens on the reflecting mirror and makes parallel the measuring light or the reference light reflected by the reflecting mirror.

摘要： A light beam deflector employs first and second surface elastic waves to diffract guided waves split from a single light beam introduced into an optical waveguide. The surface elastic waves are generated respectively by first and second tilted-finger chirped interdigital transducers or curved-finger interdigital transducers which are arranged such that the first and second guided waves emittted out of the optical waveguide will scan a surface along respective aligned scanning lines, the ends of which scanning lines are adjacent to each other. The light beam deflector allows a large image to be recorded or read out because it has a wide deflection angle range. The first and second interdigital transducers may alternatively be arranged such that the first and second guided waves emitted out of the optical waveguide will scan the surface without overlapping each other. The light beam deflector may also include third and fourth interdigital transducers for generating third and fourth surface elastic waves for further diffracting the guided waves to provide an even wider deflection angle range.

摘要： A semiconductor laser module is formed by directly bonding a semiconductor laser, which has a wavelength tuning mechanism, and an optical wavelength conversion element which exits laser beam of the second harmonic with the wavelength of the exited laser beam being the fundamental wave. A center wavelength of stimulated emission of the semiconductor laser is tunable, and is locked so as to coincide with a phase matching wavelength of the optical wavelength conversion element. The semiconductor laser and the optical wavelength conversion element are directly bonded together at an end surface portion of an optical wavelength of the optical wavelength conversion element.
