1. A method of measuring a spectral response of a biological sample, comprising the steps:

  • generation of probe light having a primary spectrum,irradiation of the sample with the probe light, including an interaction of the probe light and the sample, andspectrally resolved detection of the probe light having a modified spectrum, which deviates from the primary spectrum as a result of the interaction of the probe light and the sample, said modified spectrum being characteristic of the spectral response of the sample,whereinthe probe light comprises probe light pulses being generated with a fs laser source device;

    the detection step comprises time-domain sampling a temporal shape of the probe light pulses after the intersection with the sample, andthe spectral response of the sample is obtained based on a Fourier transformation of the temporal shape of the probe light pulses.
