    摘要: An optical system is described for scanning optical record carriers of different types. The optical system includes a compensator having a number of optical elements (NPS1, NPS2). The optical elements (NPS1, NPS2) are non-periodic phase structures (NPS) having annular areas separated by steps, forming a non-periodic pattern of optical paths of different lengths. By including these multiple optical elements (NPS1, NPS2) having NPS surfaces in the lens system of an optical system, it is possible to compensate for the effect of variation of a parameters such as temperature, angle of incidence, polarisation of radiation incident on the system and wavelength of radiation, without causing sensitivity to variation of another such parameter.

    摘要: An acoustic probe (100) includes an acoustic transducer (20) including a plurality of acoustic transducer elements arranged in a one-dimensional array; and a variably- refracting acoustic lens (10) coupled to the acoustic transducer. The variably-refracting acoustic lens has at least a pair of electrodes (150, 160) adapted to adjust the focus of the variably-refracting acoustic lens in response to a selected voltage applied across the electrodes. In one embodiment, the variably-refracting acoustic lens includes a cavity, first and second fluid media (141, 142) disposed within the cavity, and the pair of electrodes. The speed of sound of an acoustic wave in the first fluid medium is different than the speed of sound of the acoustic wave in the second fluid medium. The first and second fluid media are immiscible with respect to each other, and the first fluid medium has a substantially different electrical conductivity than the second fluid medium.

    摘要: The invention relates to an optical system comprising a fluid chamber 1 and a birefringent part. The fluid chamber comprises first and second fluids 10, 12 having different indices of refraction, the interface between the fluids forming a meniscus 14. The birefringent part is capable of varying characteristics of a first radiation beam 3b and a second radiation beam 3c, the first and second radiation beams having different polarisations. Variation in the configuration of the meniscus causes variation in the characteristics of the first radiation beam and the second radiation beam. Variation in the configuration of the meniscus may be controlled by electrowetting.

    摘要: A compact and substantially achromatic optical lens system (100, 200) comprising an electrowetting lens (104, 204) is provided. The optical lens system is using an electrowetting lens in which at least one of the entrance window surface (117, 217) or exit window surfaces (219), being in contact with one of the fluids (112, 212, 113, 213), has a curvature. When the sign of the curvature of that surface has the same sign as the curvature of the meniscus when no voltage is applied, a low building height is achieved. The optical element (104, 204) not only acts as a focussing or zooming device, but that it also acts as an aberration reduction element for the other elements in the optical lens system (100, 200).

    摘要: The invention concerns an objective lens for use with a dual layer optical information carrier. Such a carrier as used in Blu-ray Disks (BD) has a first information layer at a depth D1 below a top surface of the carrier and a second information layer at a depth D2, greater than depth D1. In accordance with the invention the objective lens is designed to produce substantially equal amounts of higher order spherical wavefront aberration when scanning the first and second information layers by providing minimum spherical aberration for scanning at a depth Dopt which is located between an average layer depth Dav=((D1+D2)/2) and a depth (D1+Dav)/2. More specifically, the optimum depth Dopt is typically smaller than 0.995 Dav and most preferably less than 0.99 Dav.
