Method and arrangement for the time-resolved spectroscopy using a photon mixing detector

摘要: The present invention relates to a solution for time-resolved spectroscopy, wherein the sample be analyzed is illuminated by modulated light source, and spectrum reflected therefrom recorded in manner evaluated. In method according irradiated source having short pulses, radiation emitted represented via imaging optical elements spectral-selective element on sensor disposed image plane, signals thereof are evaluated control regulating unit, and/or stored. plane PMD sensor, which addition intensity values also determines running times of sample, forwards same unit. Although sensors were originally intended object recognition, particularly traffic, use many other technical fields conceivable advantageous. provided herein describes analysis samples. However, possible Raman spectrometry, or measurement luminescence, such as differentiating phosphorescence fluorescence light.
