    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.

    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.

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.

    摘要: An electro-optic optical modulating apparatus comprises an optical waveguide, which has electro-optic effects, and at least a single pair of electrodes, which are located in the vicinity of the optical waveguide. A driving circuit applies a radio-frequency voltage across the electrodes. A modulating circuit modulates the amplitude of the radio-frequency voltage in accordance with a predetermined signal. The amount of a modulated optical wave is thus prevented from fluctuating due to a DC drift phenomenon.
