WebFeb 1, 2024 · In summary, a kind of dual autofocusing CAB is proposed based upon the relation between autofocal position f and initial launch angle parameter v in this paper. By combining phases of two different initial launch angles (v 1 and v 2) into light fields of CAB, the beam would have two autofocal points; v 1 determines f 1, and v 2 determines a ...

Introduction. The circular Airy beam (CAB) has attracted intensive interest since it is first proposed in 2010 [1], [2].The multiple rings of CAB focus along parabolic trajectory in free space, leading to the unique abruptly autofocusing property [3].CAB could keep a low intensity before the focal point and form a sharp light spot in the focal region, therefore it … fish restaurants burlington ncWebSep 12, 2024 · The effect is most noticeable when the aperture is small, but the effect is there for large apertures as well.
