摘要： A method of measuring a polarization response of a sample (1), in particular a biological sample, comprises the steps of generating a sequence of excitation waves (2), irradiating the sample (1) with the sequence of excitation waves (2), including an interaction of the excitation waves (2) with the sample (1), so that a sequence of sample waves (3) is generated each including a superposition of a sample main pulse and a sample global molecular fingerprint (GMF) wave (E GMF(sample) (t)), irradiating a reference sample (1A) with the sequence of excitation waves (2), including an interaction of the excitation waves (2) with the reference sample (1A), so that a sequence of reference waves (3A) is generated each including a superposition of a reference main pulse and a reference GMF wave (E GMF(ref) (t)), optically separating a difference of the sample waves (3) and reference waves (3A) from GMF wave contributions which are common to both of the sample waves (3) and reference waves (3A) in space and/or time, and detecting the difference of the sample waves (3) and the reference waves (3A) and determining a temporal amplitude of differential molecular fingerprint (dMF) waves ( ΔE GMF ) (4) each comprising the difference of the sample and reference GMF waves. Furthermore, a spectroscopic apparatus for measuring a polarization response of a sample (1) is described.
