摘要： An optical disk apparatus includes an objective lens system for producing a beam spot on an optical disk, a slider movable relative to the optical disk, and a fine tracking mechanism for shifting the beam spot in a radial direction of the optical disk. The objective lens system is composed of a first lens and a second lens. The second lens is held by the slider and disposed closer to the optical disk than the first lens is. The tracking mechanism shifts the second lens in the radial direction of the optical disk for tracking control.

摘要： A hologram reproducing device includes a splitter for splitting a reference beam, during reproduction, into a main beam and sub-beams forming incidence directions spatially shifted from the main beam. The hologram reproducing device also includes: an incidence direction variable irradiator for changing the incidence directions of the main beam and the sub-beams; a servo beam detector for detecting a portion of the reproduction beam generated in accordance with the sub-beams; and a beam receiving unit for receiving the main portion of the reproduction beam generated in accordance with the main beam. A reproducer reproduces an image obtained by the beam receiving unit when the main beam coincides with the incidence direction at which the received light of the beam receiving unit becomes equal to or greater than a prescribed level, with the intensity of the reference beam kept uniform, on the basis of the servo beam detection results.

摘要： An underground radar tomography in which an electromagnetic wave is radiated into the ground, the amplitude and propagation time of a transmitted wave, a reflected wave or a diffracted wave of the electromagnetic wave are measured at a number of points, and signal processing is performed on the result of measurement to thereby obtain the distribution of strata and soil in the ground as section information with a high accuracy. By use of two pseudo random signals which are slightly different in period but the same in code pattern, measurement time which is expanded relative to propagation time is obtained to thereby make the measurement accuracy high.
