摘要： An optical scanning device for scanning optical record carriers having cover layers of different thicknesses. The scanning device has a first mode for scanning a first optical record carrier, a second mode for scanning a second optical record carrier and a third mode for scanning third optical record carrier. The device comprises an objective lens system and a switchable optical element having a first discrete state and a different, second discrete state. The element comprises: a fluid system including a first fluid and a different, second fluid (19); a wavefront modifier (17); and a fluid system switch for acting on the fluid system to switch between the first and second discrete states of the element. When the element is in the first discrete state, the wavefront modifier (17) is substantially covered by the first fluid, and when the element is in the second discrete state, the wavefront modifier (17) is substantially covered by the second fluid (19). The wavefront modifier includes a non-periodic phase structure including a plurality of stepped annular zones separated by steps, the zones forming a non-periodic radial pattern, and is characterized in that the wavefront modifier further includes an aspherical surface. The scanning device is arranged to operate using the element in the second state to generate spherical aberration when in the second mode, the aspherical surface of the element in the second state compensating for more than half of the spherical aberration due to the objective lens system and second record carrier in combination.

摘要： An optical compensator for use in an optical scanning device for scanning a first optical record carrier (3′) having an information layer (2′) at a first information layer depth d and a second optical record carrier (3″) having an information layer (2″) at a second, different information layer depth d2. The scanning of the first and second optical record carrier is effected using a scanning spot (16) formed on the information layer by a first radiation beam having a first wavelength and a second radiation beam having a second, different wavelength respectively. The optical compensator includes a substantially circular phase structure having an annular zone arranged in the path of the first radiation beam and the second radiation beam. The annular zone is adapted for imparting a wavefront modification to said first radiation beam causing destructive interference over the area of the scanning spot (16) for radiation incident on said annular zone; and a wavefront modification to said second radiation beam for compensating spherical aberration. A further aspect of the present invention relates to an optical element for defining the numerical aperture of a radiation beam. The optical compensator or optical element can be used for a two- or three-wavelength system. The invention also discloses an optical scanning head, and an optical scanning device using the optical compensator. The invention also relates to an optical scanning head and an optical scanning device.

摘要： A method for controlling an angular distribution of a light-beam emitted by a light-output device (102, 200) comprising a first set of light-sources (105, 211) comprising at least one light-source configured to emit light within a first angular range (221, 231, 241) and second set of light-sources (107, 210) comprising at least one light-source configured to emit light within a second angular range (222, 232, 242), wherein the first angular range is different from the second angular range. The method comprises the steps of: receiving (401) a dimmer setting (VDS) from a dimmer (101); controlling (404), if the dimmer setting is within a first predetermined range, the first set of light-sources to emit light within the first angular range; and controlling (405), if the dimmer setting is within a second predetermined range, the second set of light-sources to emit light within the second angular range. Through the method according to the invention the angular distribution of light emitted from a single light-output device may be controlled using a single switch, thereby avoiding the need for having a plurality of switches and/or new wiring which would otherwise be required.
