title: Note: a resonant fiber-optic piezoelectric scanner achieves a raster pattern by combining two distinct resonances.
abstract: The resonant fiber-optic piezoelectric scanner (RFPS) benefits imaging systems with compactness and flexibility, but previously its scanning manner was limited to non-raster patterns that suffer various deficiencies (e.g., nonuniform in terms of spatial coverage and sampling time). Here, we propose a method for the RFPS to achieve a raster pattern by producing different order resonances in the two orthogonal directions. Resonant frequencies of the RFPS are deduced by the Euler-Bernoulli beam theory, and investigated by finite element method. We experimentally fabricated a prototype RFPS, measured its properties to investigate the feasibility for raster scanning, and finally demonstrated the imaging ability.
