Frequency and Phase Drift in Scanning Trajectory for Endoscopic Imaging System

Optical fibre cantilever that is on Lissajous scanning systems are widely used for optical imaging. But, this type of system is vulnerable to frequency and phase shifts. We report the theory behind the shift in Lissajous scanning trajectories caused by dynamic discrepancies in the scanning system. T...

description	Optical fibre cantilever that is on Lissajous scanning systems are widely used for optical imaging. But, this type of system is vulnerable to frequency and phase shifts. We report the theory behind the shift in Lissajous scanning trajectories caused by dynamic discrepancies in the scanning system. The impact of phase mismatch between phase response of the scanning system and driving signal during the image reconstruction was demonstrated via simulation. As long as the scanning system's phase response is correctly monitored, new opportunities for enhanced Lissajous scanning systems can be explored.
