摘要: An optical scanning device (1) for scanning at least one information layer (2) of at least one optical record carrier (3). The device includes a radiation source (7) for providing at least a first radiation beam (4) comprising a first wavelength, an objective lens system (8) for converging the first radiation beam on a respective information layer (2), an information detector (23) for detecting at least a portion of the first radiation beam (22) reflected from the respective information layer, for determining information on said layer, and a spherical aberration detection system. The spherical aberration detection system includes an aberration detector (24) for detecting at least a portion of the reflected first radiation beam for determining spherical aberration of the first radiation beam, and a diffractive element (26) for diffracting at least a portion of the reflected first radiation beam towards the aberration detector (24), and for transmitting at least a portion of the reflected first radiation beam towards the information detector (23). In a first mode of operation the grating is arranged to introduce a phase change to an incident portion of a radiation beam for transmitting that portion towards the information detector (23). In a second mode of operation the grating is arranged to introduce a phase change to an incident portion of the reflected first radiation beam for diffracting that portion towards the aberration detector (24).

摘要: An objective lens system for an optical biopsy device has a lens that comprises a first part configured for viewing at a first magnification, and a second part configured for viewing at a second magnification. The second magnification is substantially different from the first magnification. The first magnification enables viewing a larger area of a target and the second magnification enables viewing the target at a cellular level with high sensitivity and specificity. Combining viewing at two different magnifications in a single objective lens results in a compact optical biopsy device.

摘要: The present invention discloses an optical device comprising a container enclosing an insulating liquid (A) and a liquid responsive to an electric field (B), the insulating liquid (A) and the liquid responsive to an electric field (B) being immiscible and being in contact with each other via an interface (14), at least one of the liquids (A; B) being at least partially placed in a light path through the container. The optical device further comprises an electrode arrangement (2; 12) for controlling the shape of the interface (14) by means of a voltage; and means (100) for preventing the interface from an exposure to an external electric field. Consequently, the build-up of electrostatic charge on a surface of the optical device is avoided, which prevents the unwanted distortion of the interface (14) caused by the interaction of the liquid responsive to an electric field (B) and the electrostatic charge.

摘要: An acoustic probe includes an acoustic transducer having acoustic transducer elements arranged in a one-dimensional array; and a variably-refracting acoustic lens coupled to the acoustic transducer. The variably-refracting acoustic lens has a pair of electrodes configured 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 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: Fluid lens system, e.g. for medical imaging or medical treatment, with a container enclosing a fluid arranged to refract incoming waves. A pressure release mechanism is in contact with the fluid so as to compensate changes in its volume due to thermal variations, e.g. during high temperature medical cleaning. This pressure release mechanism is positioned within a pathway of incoming waves. In preferred embodiments a fluid container connected via a tube to the fluid as a reservoir, is arranged within or outside the container, e.g. beyond an image sensor. Alternatively, an easily compressible body, e.g. a small closed metal bellows enclosing a gas, is positioned inside the fluid to absorb volume changes by compression. In both embodiments, the pressure release elements are preferably positioned in a peripheral part of the pathway of incoming waves to not affect performance of the lens. In another aspect, a fluid lens includes a container with an inner container part that fits inside an outer container part, wherein the inner container part is in rigid connection to at least a one boundary arranged for penetration of incoming waves. The pressure release mechanism is positioned within the outer container part, and it is in contact with the fluid so as to compensate changes in volume of the fluid due to thermal variations. In one embodiment the inner and outer container parts are arranged for relative one-dimensional movement and fluid tight interconnected. In another embodiment, a fluid filled cavity is formed between the inner and outer container parts, and this cavity houses a compressible body. The lens systems are suited for applications such as medical endoscopes, catheters and needles, optically as well as acoustically based.

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.
