    摘要： The present disclosure relates to a modulator for a digital amplifier and a device comprising such a modulator and a digital amplifier.The modulator includes a pulse shaper and a control unit for controlling the pulse shaper to convert an input signal into a bit stream configured for a digital amplifier which encodes an amplitude value per clock of a carrier signal. The pulse shaper can represent a respective amplitude value of the input signal with different bit patterns. The control unit includes an assignment of the control commands to associated amplitude values resulting from amplification of the associated bit patterns with the digital amplifier is stored or at least is provided in that the control unit selects a control command per clock by means of the assignment and the amplitude value of the input signal and drives the pulse shaper accordingly.

    摘要： Optical systems and methods for spectroscopy are described. The optical system may be particularly suitable for Raman spectroscopy and includes a multispectral excitation source, designed to emit monochromatic excitation radiation successively at at least two different excitation wavelengths along a common beam axis; an elongated flow volume with a longitudinal axis, designed to direct a particle flow along the longitudinal axis; an excitation beam path, designed to irradiate the monochromatic excitation radiation into the flow volume at a first position and the second position that are located in the flow volume and the first position is spaced apart from the second position; and a detection device, designed to wavelength-selectively filter and detect a portion of a radiation scattered from the first position at a first filter wavelength and to wavelength-selectively filter and detect a portion of a radiation scattered from the second position at a second filter wavelength.

    摘要： The invention relates to a light-conducting device (60).The light-conducting device (60) comprises k>1 first deflection devices (U11, U21, U31, Sp1, Sp3) that are parallel to one another and arranged along a first direction (X), and k second deflection devices (U12, U22, U32, Sp2, Sp4) that are parallel to one another and arranged along a second direction (Y) perpendicular to the first direction. A third direction (Z) is perpendicular to the first and second direction (X, Y). Each of the second deflection devices (U12, U22, U32, Sp2, Sp4) is arranged in a same fourth direction (P) with respect to one of the first deflection devices (U11, U21, U31, Sp1, Sp3). The first deflection devices (U11, U21, U31, Sp1, Sp3) comprise optical axes directed in a fifth direction, and the second deflection devices (U12, U22, U32, Sp2, Sp4) comprise optical axes directed opposite to the fifth direction. The fifth direction is an angle bisector of an angle between the third and the fourth direction.
