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.

We developed a confocal microscope and ultra-spectral light source containing Liquid Crystal Arrayed Microcavities (LCAM) as a new technology for controlled ultra-narrow optical filtering (FWHM ∼0.1 nm). LCAMs use picoliter volume Fabry–Perot-type optical cavities filled with liquid crystal for wavelength tuning. With sub-nanometer spectral resolution, we measured spectral resonance from scattering particles to validate the measurements with simulation results. We measured chicken liver and breast muscle, pig skin and muscle and compared with results from literature. The main application is the estimation of nuclear size in biological tissues for noninvasive assessment equivalent to histopathology.
