摘要： An optical focusing device for focusing an incident optical beam onto a focal plane, as a focal spot. The optical focusing device includes an incident central refractive facet upon which an optical beam impinges, and a high-index glass body through which the incident optical beam passes toward a bottom reflective surface. The bottom reflective surface reflects the optical beam through the body, toward a peripheral reflector. The peripheral reflector focuses the optical beam toward a focal plane on which the focal spot is formed. The focal plane is defined within a pedestal that forms part of the optical focusing device, and that extends from the bottom reflective surface. The central facet is conically shaped for refracting the incident optical beam away from the pedestal, onto the bottom reflective surface. The peripheral reflector surrounds the central facet and can have various appropriate shapes, such as an aspherical shape or a tilted parabolic shape, which compensates for the conical factor and aberrations introduced by the central facet. The top surface includes the central facet and the peripheral facet, and can be made substantially flat using diffractive optical elements or Fresnel optics. The focal spot of the optical rays can be optimized using sequential quadratic program and a set of optimized coefficients.

摘要： A silicon substrate is disposed parallel with an optical disc. A prism for transmitting an incident beam is installed on the silicon substrate. A diffraction grating on a side surface of the prism. A beam splitter for partially reflecting and partially transmitting the laser beam is positioned inside of the prism to be slanted. The beam irradiated from the laser light source is reflected by the beam splitter after having transmitted through the diffraction grating. The reflected beam focuses onto the optical disc via a selective light-transmitting part formed on the upper surface of the prism. The beam is totally transmitted through an inner circular portion of the selective light-transmitting part and half transmitted through a peripheral portion of the selective light-transmitting part. The beam reflected from the optical disc partially is transmitted through the beam splitter, and then reflected a reflecting layer formed on the lower surface of the prism, and received a photodetector formed on an upper surface of the prism.

摘要： A mirror assembly of micron dimensions for use in deflecting beam of light. The mirror assembly includes a planar base and a planar mirror spaced apart from the planar base and disposed generally parallel to the planar base. The planar mirror has first and second end portions and a longitudinal axis extending between the first and second end portions. First and second torsional members extend along the longitudinal axis and are connected to the respective first and second end portions for permitting the mirror to rock between first and second positions about the longitudinal axis relative to the planar base. The first and second torsional members are secured to the planar base. At least a portion of the mirror is made from a conductive material. First and second spaced-apart electrodes are carried by the planar base for driving the mirror between the first and second positions. A tether member extends transversely of the longitudinal axis and is secured to the first torsional member and to the planar base. The tether member regulates the rocking of the mirror.

摘要： A light source module with two wavelengths that is adapted to generate laser beams different in wavelength. In the light source module, a hologram optical element (HOE) is used to allow a first laser beam generated at a first light source and a second laser beam generated at a second light source to progress along same path. The HOE diffracts the second laser beam to change a progressive path of the second laser beam into that of the first laser beam. The first light source generates the first laser beam having a different wavelength from the second laser beam generated at the second light source.

摘要： A first objective lens and a second objective lens are fixedly mounted on a lens holder. The lens holder has four magnetic members embedded in a side thereof about an axis of rotation. The magnetic members are associated with coils respectively. The lens holder is rotatable supported by a support which has four permanent magnets fixedly mounted on a side thereof corresponding to the four coils. A pair of the magnets located opposite to each other is for the focusing control and the other pair of the magnets located opposite to each other is for the tracking control and the objective lens switching control. When the coils corresponding to the magnets are loaded with a switching signal, they turns the lens holder to switch the objective lenses from one to the other. When the coils corresponding to the magnets are loaded with a tracking drive signal, they perform the tracking control. When the coils corresponding to the magnets are loaded with a focusing drive signal, they perform the focusing control. At the beginning of operation, the objective lens drive apparatus can be initialized by feeding the switching signal to either pair of the coils so that the objective lens is set across a light path.

摘要： An electro-optical storage system based on a near-field configuration having phase-distortion reducing mechanism. The system comprises a read/write head and a head positioning system, an optics module including beam relay optics and signal detectors, an optical medium and a corresponding medium driving unit, and an electronic control system. The optical head includes a near-field lens positioned over the optical medium by a fraction of the wavelength. The phase-distortion reducing mechanism imposes a phase-compensating profile on the optical wavefront and/or rotates the beam polarization to reduce a phase distortion caused by the lens aberrations and an extra phase profile induced by the near-field configuration.
