a Schematic of active phase modulation-assisted D-FFOCT. BS, Beam splitter; OB, Objectives; PZT, piezoelectric translation; YAG, Yttrium Aluminum Garnet. The signal generator provides an active modulation signal to the PZT in the reference arm. b An intensity trace that records the temporal fluctuations of back-scattered light from a pixel of the camera. c Frequency spectrum obtained by Fourier transform of the intensity trace.
