Observation of resonance harmonics for monocytes. For statistical analysis a 4 × 4 scan was performed in the nuclei of 20 cells. (a) Top-view white light images of some of these monocytes. (b) Linear correlation between the two high frequency components \({f}_{1}^{H}\), \({f}_{2}^{H}\) and the fundamental frequency (fR).
