摘要： An object of the present invention is to attain stable tracking servo performance by suppressing an offset caused by a shift of an object lens or a tilt of a disk, despite the one-beam method which does not cause reduction in light quantity of the main beam. A diffraction grating is provided between a hologram and a light receiving section, and a diffraction efficiency of the diffraction grating is varied in a grating longitudinal direction. For example, if an incident light beam on the diffraction grating is shifted in the grating longitudinal direction, the quantity of received light in each light receiving section varies to cause offset. By performing tracking servo so as to cancel the change, it is possible to correct the offset, thereby attaining stable tracking servo performance.

摘要： In order to accurately measure a shape feature of a minute droplet arranged on a substrate by a simple method, with respect to the droplet, the substrate is perpendicularly irradiated with laser light to cause diffracted light fluxes generated during passage of the laser light through the droplet to interfere with each other, so that a diffraction pattern is obtained. The diffraction pattern formed on a screen of a detector as an image is picked up by an image pickup apparatus. The shape feature of the droplet is measured by using the resultant diffraction pattern and a refractive index of the droplet.

摘要： An objective lens driving apparatus includes a base, an objective lens for converging an optical beam on an optical disc while the optical disc is rotating, and a holding member for holding the objective lens. A first supporting mechanism elastically supports the holding member on the base in such a manner as to allow the holding member to be translated in a focusing direction which is substantially perpendicular to a surface of the optical disc and in a tracking direction which is substantially perpendicular to the focusing direction and parallel to a radial direction of the optical disc. A moving mechanism including a coil and a magnetic circuit for translates the holding member in the focusing direction and the tracking direction by a driving force generated by the coil and the magnetic circuit. A second supporting mechanism for visco-elastically supports the magnetic circuit on the base in such a manner as to translate the magnetic circuit in the focusing direction. The magnetic circuit is translated in an opposite direction to the translation direction of the holding member by a driving force acting oppositely to the driving force for translating the holding member in the focusing direction.
