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： A method for detecting the presence of inhomogeneities in an interior of a turbid medium (1) is provided. The method comprises the steps: performing a first measurement with the turbid medium (1) to be examined placed in a receiving volume (2) of a device for examining the interior of turbid media; performing a second measurement with the turbid medium (1) to be examined placed in the receiving volume (2) of the device for examining the interior of turbid media. The second measurement is performed after a time interval (Δt) has passed after the first measurement. Each of the first and second measurements comprises: subsequently irradiating the turbid medium (1) with light from at least one light source (6) from a plurality of different source positions and detecting light emanating from the turbid medium in a plurality of different detection positions for each source position, and storing the detected values as measurement results. The method further comprises the step: detecting inhomogeneities in the interior of the turbid medium (1) by using the measurement results of one of the first and second measurements as a reference and the measurement results of the respective other of the first and second measurements to determine deviations from the reference.
