Fully packaged confocal endomicroscopic system using Lissajous fiber scanner for indocyanine green in-vivo imaging

Abstract

This work presents a fully packaged confocal endomicroscopic system using Lissajous fiber scanner for in-vivo imaging. The confocal endomicroscopic system consists of a scanning probe part, an optical part, and an electrical part. The scanning probe uses resonant Lissajous fiber scanner based on a piezoelectric tube. The scanner successfully achieves 10 frame rate with ~ 1 kHz scanning frequencies. The probe was fully packaged for waterproofing and disinfection of medical instruments into the outer diameter of 3.4 mm. The endomicroscopic system and successfully obtained 2D reflectance imaging results, human ex-vivo imaging results and a real-time in-vivo imaging results.
