Endoscopic optical probes for linear and rotational scanning

摘要

Two fully integrated optical microprobes, based on an advanced silicon optical bench (SiOB) technology, are developed for endoscopic OCT (optical coherence tomography). The probes incorporate diverse optical components and scan mechanics, such as magnetostatic micromirrors and rotating prisms, to realize linear side-looking and rotational scanning. The outer diameter of the assembled systems is below 2.75 mm allowing integration into the 3mm working channels of commercial endoscopes.
