    摘要： The present invention relates to a higher-order dispersion compensation device (210), the device being adapted to cooperate with a pair of optical components (P1, P2), e.g. a pair of prisms, being arranged to compensate first-order dispersion by separating different wavelengths spatially. The compensation device (210) has the form of a phase plate, wherein the phase change for each wavelength is adjusted by designing the height (h) at the corresponding position (x) of the plate so as to substantially compensate for higher-order dispersion. The invention is advantageous for obtaining a higher-order dispersion compensation device which is relatively simple to construct and use making it a quite cost-effective device. The invention also relates to a corresponding optical system and method for compensating dispersion where this is important, e.g. in a multiple-photon imaging system.

    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： The present invention relates to an optical probe (1) with an optical guide (2), e.g. an optical fibre, and a lens system (6) rigidly coupled to an end portion (2a) of the optical guide. The probe has a housing (3) with a cavity for the optical guide, the housing having at its distal end a transparent window (4), the window having an insignificant optical power as compared to the optical power of the said lens system (6). Actuation means (8) displaces the 5 lens system so as to enable optical scanning of a region of interest (ROI). The invention is particularly suited for miniature applications e.g. for in-vivo medical application. By attaching the lens system (6) to the optical guide (2) via the mount (7), the field of view (FOV) of the optical probe (1) may be determined directly by the transverse stroke of the optical fibre (2). Hence only a relatively small stroke is required. The field of view is thus 10 effectively no longer limited by the transverse stroke. The optical probe is especially advantageous for non-linear optical imaging where the optical guide may be an optical fibre with a relatively low exit numerical aperture.

    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.
