Abstract

This article presents the results of a study focused on the development of an integrated probe intended for endomicroscopic application. A new type of transverse scanning probe is described, which was built using Mirau microinterferometer fabricated in micro-opto-electromechanical systems (MOEMS) technology, and a two-axis electrothermal actuator fabricated in micro-electromechanical systems (MEMS) technology, connected with a gradient-index (GRIN) lens collimator and single-mode fiber. Herein, we present a numerical analysis and an optimization of endomicroscopic probe-scanning properties, based on Lissajous curves. The key part of this article is 2-D and 3-D imaging of phantom structures, based on polymer material, light-scattering material, and USAF-target pattern visualized with an endomicroscopy probe. The imaging was obtained by the swept source optical coherence tomography (SS-OCT) technique, working at a central wavelength $\lambda _{c}$ = 1060 nm, a swept range $\Delta \lambda $ = 100 nm, an A-scan rate ${f}_{a}$ = 200 kHz, and the scanning of samples with the use of Lissajous curves.

Abstract

International audience; In this paper, we present the construction and preliminary experimental results of a MOEMS fiber-based integrated probe for endoscopic optical imaging of stomach tissue using a Swept-Source Optical Coherence Tomography (SSOCT). The probe consists of a Mirau micro-interferometer, combined with a GRIN lens collimator and a micromirror scanner. We describe the building blocks of the probe, especially the monolithically integrated Mirau mirointerferometer, fabricated by wafer-level vertical stacking and anodic bonding of Si/glass components, and the electrothermal 2-axis MEMS microscanner allowing large swept angles (up to ±22°) at high frequencies (&gt kHz) for low driving voltages (
