摘要
An optical fiber for generating a Bessel beam and an optical imaging device using the same are disclosed. The optical fiber for generating a Bessel beam includes a single mode optical fiber (SMF) unit, a multi-mode optical fiber unit, and a lens unit. The SMF unit includes a core and a cladding surrounding the core. The multi-mode optical fiber unit comes in contact with a first end of the SMF unit. The lens unit comes in contact with one end of the multi-mode optical fiber unit that faces the first end of the SMF unit.
