Dual-comb Spectroscopy with OAM modes for Azimuth Angle Measurement

Akifumi Asahara and Kaoru Minoshima

Not Accessible

Your library or personal account may give you access

Abstract

By combining dual-comb spectroscopy and optical vortices, in-plane azimuth angle measurement was performed based on optical frequency combs. The measurable angle range was tailored by the topological charge number of the involved optical vortices.
