Abstract

Conventional laser scanning mechanisms, such as MEMS mirrors and piezoelectric tubes, are often complex to fabricate and limited in their fields of view. We developed a distal laser scanning platform that is scalable for both high performance and low resource settings given its low cost and low voltage requirements. Our platform enabled a customisable array of resonantly scanning optical fibers to be mounted on the top and/or bottom of a piezoelectric bender. Parallel scans were combined to generate multiplexed multi-millimeter fields of view at low voltage drives. We explored the bender’s potential as an endomicroscopic scanning platform by demonstrating its use in the depth-multiplexed OCT imaging of a fingertip and 3D cell culture.
