摘要： Methods of optimizing optical alignment in an optical package are provided. In one embodiment, the optical package includes a laser diode, a wavelength conversion device, coupling optics positioned along an optical path extending from the laser diode to the wavelength conversion device, and one or more adaptive actuators. The method involves adjusting the optical alignment of the wavelength conversion device in a non-adaptive degree of freedom by referring to a thermally-dependent output intensity profile of the laser diode and a thermally-dependent coupling efficiency profile of the optical package. The adjustment in the non-adaptive degree of freedom is quantified such that, over a given operating temperature range of the optical package, portions of the coupling efficiency profile characterized by relatively low coupling efficiency offset portions of the output intensity profile characterized by relatively high laser output intensity and portions of the coupling efficiency profile characterized by relatively high coupling efficiency offset portions of the output intensity profile characterized by relatively low laser output intensity. Additional embodiments are disclosed and claimed.

摘要： A prism is attached to a refractive index dispersion lens by inclining the incident plane of the prism by a prescribed angle with respect to the end face of the refractive index dispersion lens and filling adhesive therebetween. In this way, the amount of light reflected from the bottom plane of the prism decreases in accordance with the angle of inclination of the incident plane, and the interference signal formed by the reflected light from the bottom plane of the prism, and the reflected light of a reference beam therefore weakens and the image signal decreases. Consequently, distinguishing between the image signal and the image signals produced by reflected light from the measurement subject is facilitated.

The reflecting surface 71a of the mirror reflects the first to second light beams and guides them to the objective lens. Reflecting surface 70a reflects the third light beams and guides them to the objective lens. The phase structure on the objective lens corrects the spherical aberration of the first and the second light beams, and focuses the first light beams onto BD, the second beams onto DVD and the third beams onto CD.

摘要： Provided are an optical connector and an optical tomographic imaging apparatus, by which no noise occurs and a high quality image without a distortion can be obtained. In the optical connector, optical fibers are inserted into a lumen of a tube from opposite ends thereof; one of the optical fibers is fixed to the tube and the other optical fiber is held so as to be rotatable relative to the tube; an end of one of the optical fibers is separated from an end of the other optical fiber to form a gap therebetween in the lumen; a connecting section which connects the exterior space of the tube and the gap is formed; and a liquid or fluid made of a material which can transmit light is held in the exterior space, the gap, and the connecting section. Consequently, a significant pressure variation in matching liquid does not occur if the distance between the facing optical fibers changes.
