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) withthe 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 asample main pulse and a sample global molecular fingerprint (GMF) wave (EGMF(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 (EGMF(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 dete
