Abstract

Two novel MEMS actuator systems (a torsional one and a deflecting one) for a new self-aligned integrated 3D optical coherent tomography (OCT) scanner are reported. These new systems, with a footprint of 2.5mm×2.5 mm each, provide a χ and y scanning range of 730 μm (tilting range of 8°) with an average power consumption of 150 mW. As the device integrates a silicon collimating micro lens, an optical waveguide and a MEMS actuator system on a single chip, it provides a considerable decrease in optical losses thanks to the intrinsic alignment obtained during fabrication, while significantly reducing the complexity and time that assembly and packaging of separate components demand, therefore making fully integrated, miniaturized 3D OCT scanners feasible.
