Keywords:Optical comb, Optical vortex, Orbital angular momentum

We have proposed a concept of "optical-vortex-comb," which realizes precise spatiotemporal phase control by combining optical comb and optical vortex. In this study, we applied a measurement method combining “dual-comb spectroscopy” and “single-pixel imaging” to optical phase characterization of complex multiplexed optical vortices. Our result is expected as novel optical technology in a wide range of fields such as waveform shaping of optical vortices, chiral material study, and optical communication using transverse optical modes.
