摘要： A method of measuring the origin and amount of a shear between a basic light beam and a reference light beam in a shearing interferometric system. To detect the shear origin, shutters are disposed respectively in the optical paths of the basic and reference light beams. The basic and reference light beams are guided through a condenser lens toward a four-segment light detector. First, the optical path of the reference light beam is closed to allow only the basic light beam to fall on the four-segment light detector. By adjusting the position of the light detector, the position of the basic light beam is identified. Then, the optical path of the basic light beam is closed to allow only the reference light beam to reach the light detector. While output signals from the light detector are being monitored, a shearing member is displaced to shift the reference light beam to detect the shear origin in which the reference and basic light beams are overlapped. To measure the shear amount, light of a plane wave is used as the basic light beam, and the basic and reference light beams caused by an imaging lens to fall on an area sensor are of plane wavefronts. An interference fringe pattern on the area sensor is measured by a fringe scanning process to determine an angle at which the wavefronts of the basic and reference light beams are inclined to each other. The shear amount is computed from the determined angle and the focal length of the imaging lens.

摘要： An optical pickup apparatus couples light beams, and corrects a chromatic aberration and a spherical aberration. A coupling lens includes groups of lenses common to the light sources so as to converge a light beam from each of the light sources. An aperture changes an aperture diameter for the light beam, which has been converged by the coupling lens, in accordance with one of the light sources from which the light beam is emitted. An objective lens converges the light beam onto a recording surface of one of the optical information recording media corresponding to the one of the light sources that emits the light beam. A lens moving mechanism moves at least one group of lenses from among the groups of lenses of the coupling lens in a direction of an optical axis thereof in accordance with an aperture diameter of the aperture.

摘要： An objective lens causes light emitted from the light source to converged onto an optical recording medium. A beam splitter separates light, reflected from the optical recording medium, from the bundle of rays emitted from the light source. A detective lens causes the light separated by means of the beam splitter to be converged. A detective photosensitive element is disposed at a position at which the light converged by means of the detective lens approximately converges. The detective lens has a first and second surfaces. The first surface faces the beam splitter and is formed to be convex so as to cause the bundle of rays to converge. The second surface comprises two surfaces which are combined with one another so that the line of intersection, formed where the two surfaces meet, does not intersect the axis associated with the convexity of the first surface.

摘要： A focusing method for interferometer wherein a light flux passing through a converter lens for converting the shape of wave fronts is caused to be incident on a tested surface and a testing light beam reflected by the tested surface is caused to be incident on a light receiving element capable of measuring the distribution of intensity of the light at least one-dimensionally. The tested surface is moved in the direction of its center axis until it reaches a position in which the vertex of the tested surface coincides with the focus of the converter lens and the output of the light receiving element shows a peak value, and the tested surface is further moved, from the position referred to hereinabove which serves as a reference position, in the direction of its center axis.
