Abstract: A zoom lens system has, from the object side, a first lens unit, a second lens unit with an aperture stop, and a third lens unit. In this zoom lens system, zooming is performed by varying the distances between these lens units; focusing from the infinite distance to the closest distance is performed by moving the first lens unit toward the object side along the optical axis; image blur compensation is performed by decentering an image blur compensating lens unit included in the third lens unit.

Abstract: An object is to provide a image projection device which has a small size but can project an image having a high image quality. To achieve the object, in an image projection device, a reflection part which reflects a light flux from a light source is, while being rotated around a first axis by non-resonance driving, rotated by resonance driving around a second axis which is substantially perpendicular to the first axis, and thereby the light flux is deflected in a two-dimensional direction. By controlling the rotation of the reflection part, a correction for suppressing an image distortion along one scanning direction on a projection surface, and a correction for keeping substantially constant a scanning speed of the light flux along the other scanning direction on the projection surface, are performed. Here, the relationship of 10°

Abstract: A two-dimensional image is displayed on a screen (SC) by scanning the screen (SC) two-dimensionally with light beams from a laser light source (1) that are deflected to orthogonally-intersecting first and second scanning directions by means of a mirror (10) in a deflection apparatus (3). The deflection apparatus (3) is arranged to incline obliquely in the second scanning direction (e.g. vertical direction) lower in a scanning speed than the first scanning direction (e.g. horizontal direction), and performs an oblique projection onto the screen (SC). Assuming a direction in which the incidence angle of a light beam deflected by the deflection apparatus (3) and entering the screen (SC) increases in the second scanning direction is positive side, the light beam from the laser light source (1) impinges on the deflection apparatus (3) from the negative side in the second scanning direction, and the normal to the mirror (10) in the deflection apparatus (3) in a state where the center of the screen is displayed inclines to the negative side in the second scanning direction with respect to the normal to the screen (SC).

Abstract: A recorder has a recording medium for information recording, a light source, an optical system, a slider, and an optical waveguide. To the optical system, light from the light source enters, and the slider moves relative to the recording medium while not in contact therewith. The optical waveguide is arranged at position facing the recording medium in the slider so that light entering from the optical system is irradiated on the recording medium. Where the mode field diameter of the optical waveguide on the light output side is d and the mode field diameter thereof on the light input side is D, the mode field diameter is converted by smoothly changing the diameter of the optical waveguide to satisfy D>d.

Abstract: An object of the present invention is to provide an image projector capable of projecting a high-quality image while realizing small size. In the image projector, a light flux is deflected two-dimensionally by turning a reflector for reflecting a light flux emitted from a light source around a second axis almost orthogonal to a first axis as a center by resonant drive while turning the reflector around the first axis as a center by non-resonant drive. Shape of one or more optical surfaces of a projection optical system for projecting an image onto a projection plane by guiding light onto the projection plane includes a shape for performing a correction for maintaining scanning speed of the light flux along one scan direction on the projection plane almost constant and a shape for performing a correction for suppressing a distortion in an image along the other scan direction almost orthogonal to the one scan direction on the projection plane. By controlling turn of the reflector, at least one of a correction for maintaining scanning speed of the light flux along the other scan direction on the projection plane almost constant and a correction for suppressing a distortion in an image along the one scan direction on the projection plane is performed.

Abstract: A catadioptric objective system used for storage and/or reproduction of information by use of an optical near field. The catadioptric objective system is composed of a catadioptric objective lens and a light transmitting plate. The lens has a first surface and a second surface. The first surface has a positive optical power and transmits incident rays. The second surface has a positive optical power and reflects incident rays, and a plane portion is formed in the center of the second surface. The light transmitting plate has a third surface and a fourth surface which are substantially parallel to each other, and the third surface is bonded to the second surface. Incident rays pass through the first surface and are reflected by the second surface. Thereafter, the rays enter into the first surface again and are reflected by the first surface. Then, the rays pass through the plane portion of the second surface, and the rays are converged in vicinity of the fourth surface.

Abstract: A light-condensing head has a light source unit, a light-condensing element that condenses the light emitted from the light source unit, and an electrically conductive scatterer that, when irradiated with light, produces localized plasmon at the light condensation position of the light from the light-condensing element. The light emitted from the light source unit contains, at least in part thereof, polarized waves that constitute a rotation-symmetric radiating electric field vector distribution in which the electric field vectors have equal magnitudes at equal distances from the center of rotation symmetry. The electrically conductive scatterer has, in the light-receiving portion thereof that receives the light from the light-condensing element, rotation symmetry of order three or more.
