摘要： An electrowetting module (20) comprises a fluid chamber (8) which contains a first fluid (A) and a second fluid (B), which are separated by an interface (14), and means to (16,17) exert a force on at least one of the fluids to change the position and/or shape of the interface. By providing at least one of the fluids with a compound having at least one aromatic, non-fused, residue, the performance of the module can be enhanced. For example the optical power of an electrowetting lens (30) can be increased.

摘要： A variable lens includes a chamber defined by at least one side wall and has an optical axis extending longitudinally through the chamber. The chamber contains a first fluid and a second fluid contact over a meniscus extending transverse the optical axis. The perimeter of the meniscus is constrained by the side walls. The fluids are substantially immiscible, and have different indices of refraction. At least one pump is arranged to controllably alter the position of the meniscus along the optical axis by altering the relative volume of each of the fluids contained within the chamber.

摘要： An optical scanning device (1) for scanning three information layer (2, 2′, 2″) with three respective radiation beams (4, 4′, 4″) having three respective wavelengths (λ1, λ2, λ3) and polarizations (p1, p2, p3). The three wavelengths differ from each other. At least one of the three polarizations differs from the others. The device comprises a diffractive part (24) including a pattern of pattern elements which have one stepped profile for forming three diffracted beams (15, 15′, 15″) from the three radiation beams, the part comprising birefringent material, sensitive to the three polarizations. The stepped profile is designed such that the heights (hj) of the steps of a pattern element introduce phase changes that equal at least two different multiples of 2π for one (λ1) of the three wavelengths and equal at least two different phase changes modulo 2π for one (λ2) of the two other wavelengths.

摘要： A device for scanning a first and second type of optical record carriers (2, 40) generators a first and a second radiation beam for scanning the first and second type of record carriers, respectively. The information layers (4, 42) of the first and second type of record carriers is scanned through transparent layers (3, 41) of different thickness. The first radiation beam (17) has a first wavelength and a first numerical aperture NA−1. The second radiation beam (46) has a different, second wavelength and an effective second numerical aperture NA2 smaller NA1. The rays of the second radiation beam having an NA smaller than NA2 form a central sub-beam (48), the rays having a larger NA form an outer sub-beam (49). The device includes a non-periodic phase structure that does not affect the first radiation beam. The phase structure introduces an amount of spherical aberration in the central sub-beam (48). The phase structure is transparent for the central and outer sub-beam (48, 49). The introduced spherical aberration compensates the difference in spherical aberration caused by the difference in thickness of the transparent layer (3, 41) of the first and second type of record carriers (2, 40). To reduce the amount of stray light falling on the detection system (25) from rays in the outer sub-beam (49), the phase structure introduces an amount of defocus in the second radiation beam (17). The defocus displaces the focus of the central sub-beam with respect to the focus of the outer sub-beam, causing the intensity distribution of the central and outer sub-beam split in two separate distributions. If the position and size of the detection system are properly chosen, the detection system will capture mainly rays from the central sub-beam and not from the outer sub-beam. Hence, the displacement of the foci allows spatial filtering in the plane of the detection system (25) of the desired and undesired rays of the second radiation beam.

摘要： The present invention relates to an apparatus, a method and a computer program for determining a lipid-water ratio and a scattering parameter of a sample. In particular, the invention relates to an apparatus comprising a light source and a detector arranged to measure an optical parameter at various wavelengths, where the wavelengths are selected so that at two of the wavelengths the absorption coefficients for both water and lipids are substantially identical. This enables determination of a scattering parameter. A further measurement at a third wavelength enables determination of a water-lipid ratio. According to a specific embodiment, the light source and the detector are arranged in relation to an interventional device, so as to be able to examine a tissue in terms of lipid-water ratio and scattering during an intervention.

摘要： An acoustic probe (100, 300) includes an acoustic transducer (15, 444), and a plurality of variably-refracting acoustic lens elements (10, 210a, 210b, 442) coupled to the acoustic transducer. Each variably-refracting acoustic lens element has at least a pair of electrodes (150, 160) adapted to adjust at least one characteristic of the variably-refracting acoustic lens element in response to a selected voltage applied across the electrodes. In one embodiment, each variably-refracting acoustic lens element 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.
