    摘要: A medical ultrasound device is disclosed. The device comprises an elongated body having a proximal end, a distal end (10) and a distal end region (1). One or more ultrasound transducers (4) for generating acoustic radiation are positioned in the distal end region, inside the elongated body. A transmission element (5) which is substantially transparent to acoustic radiation is positioned in the radiation path of the acoustic radiation, and a controller unit is operatively connected to the ultrasound transducer. The controller unit detects the acoustic path length through the transmission element and determines the temperature at the distal end from the detected acoustic path length. In an embodiment, the medical device is an ultrasound RF ablation catheter.

    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 invention relates to a light-emitting apparatus (100) comprising an optical waveguide, particularly an optical fiber (1), for guiding a primary light beam (Bprim) into a light-splitting unit (101) which splits it into two or more partial light beams (B1, B3, B4) which are emitted in different directions and have different optical qualities, e.g. different spectral compositions or polarizations. The apparatus may optionally comprise a detector (4) for determining a Doppler shift (Δλi) in reflected light reentering the light-splitting unit (101). This renders it possible to measure simultaneously two or more spatially independent vector components of the flow velocity of a fluid, particularly of blood, surrounding the light-splitting unit (101).
