Study on the scanning system for deep focused beam by Axicon (Proceedings Paper)

Axicon produces a deep focused Bessel beam whose transverse focal spot is smaller than the size of an airy disk produced by conventional lens with the same numerical aperture. Rieko Arimoto et al. applied axicon to a beamscanning system and established the beam-scanning imaging system which is free from need of precise positioning. Meanwhile, the allowed amount of rotation is severely restricted due to the unwanted tilt in the focused ring. We analyze the tilt in the focused ring quantitatively and sugg
