Lissajous fiber scanning for forward viewing optical endomicroscopy using asymmetric stiffness modulation

Optics Express, 2014
We report a fully packaged and compact forward viewing endomicroscope by using a resonant fiber scanner with two dimensional Lissajous trajectories. The fiber scanner comprises a single mode fiber with additional microstructures mounted inside a piezoelectric tube with quartered electrodes. The mechanical cross-coupling between the transverse axes of a

Acquisizione di immagini da microscopia laser mediante figure di Lissajous

, 2008
A new equipment was designed to acquire images of a sample in a non-linear scanning microscope. The sample is scanned by means of modified Lissajous trajectories, allowing best performance of mechanical system and reduced acquisition ...

Three-dimensional eye motion correction by Lissajous scan optical coherence tomography

Biomedical Optics Express, 2017
A three-dimensional optical coherence tomography imaging method based on Lissajous scanning is presented. This method was designed to correct eye motion in OCT images. A Lissajous scanning pattern, which has a trajectory that frequently overlaps with itself, is adopted as the OCT scanning protocol to obtain measurement data.

Direct Phase Correction in Phase Locked Loop for Robust Lissajous Scanning of Resonant MEMS Mirrors

This paper proposes the direct phase correction phase locked loop (DPCPLL) for simple and robust synchronization of two resonant MEMS mirrors for a Lissajous scan. The DPCPLL, used in a master-slave synchronization structure, runs the slave mirror at the

Angular resolution and scanning density estimation based on a 3D to 2D Lissajous transition

Optics Express
Angular resolution and scanning density are important factors affecting the quality of Lissajous images. In this work, the transition characteristics from 3D to 2D Lissajous scanning curves and the relationship between 3D Lissajous scanning rotation and phase change were studied.
