The function of feedback control circuits provides the output signal to be fed back to the scanner enabling correcting the drive waveform in real-time to conquer the limitation of scanning stability of the MEMS scanner. In this study, we have developed a swept-source optical coherence tomography (SS-OCT) system configuration of a dual-axis MEMS scanner, switchable operated between open-loop and closed-loop driving modes, to investigate the scanning stability of the MEMS scanner by analyzing the scanning trajectories detected by the position sensitive device (PSD) sensor at frame rates of 50 and 250 Hz. Preliminary results of the quantitative analysis are presented in this paper.comparison of image quality | feedback control | MEMS scanner | OCT | scanning stabilityconference paper10.1117/12.30081582-s2.0-85176098858https://api.elsevier.com/content/abstract/scopus_id/85176098858
