Abstract

This paper presents a two-dimensional (2-D) MicroElectroMechanical system (MEMS) scanner that enables dual-axes confocal microscopy. Dual-axes confocal microscopy provides high resolution in both transverse and axial directions, and is also well-suited for miniaturization and integration into endoscopes for in vivo imaging. A gimbaled MEMS scanner is fabricated on a double silicon-on-insulator (SOI) wafer (a silicon wafer bonded on a SOI wafer) and is actuated by self-aligned, vertical, electrostatic combdrives. The imaging capability of the MEMS mirror is successfully demonstrated in a breadboard setup. Reflectance images with a field of view (FOV) of 344 μm × 417 μm are achieved at 8 frames per second. The transverse resolution is 3.94 μm and 6.68 μm for the horizontal and vertical dimensions, respectively.
