Abstract

A method of measuring a spectral response of a biological sample (1), comprises the steps generation of probe light having a primary spectrum, irradiation of the sample (1) with the probe light, including an interaction of the probe light and the sample (1), and spectrally 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 (1), said modified spectrum being characteristic of the spectral response of the sample (1), wherein the probe light comprises probe light pulses (2) being generated with a fs laser source device (10). Furthermore, a spectroscopic measuring apparatus is described, which is configured for measuring a spectral response of a biological sample (1).

Description

technical field [0001] The present invention relates to a method of measuring the spectral response of a biological sample. In particular, the present invention relates to a method for measuring the spectral response by illuminating a sample with broadband probe light and sensing the spectral change of the probe light resulting from the interaction of the probe light with the sample, as a method for measuring the intensity of the probe light in the sample. method of absorption and / or reflection. Furthermore, the invention relates to a spectroscopic measuring instrument for measuring the spectral response of a biological sample, said spectroscopic measuring instrument comprising in particular a broadband light source for illuminating the sample with probe light; and a detector arrangement, said The detector arrangement is used for spectrally resolved detection of changes in the probe light resulting from the interaction of the probe light with the sample. The invention can be...
