title: Generation and scanning of Airy beams array by combining multiphase patterns.
abstract: The method of superimposing multiple phase patterns to generate and deflect multi Airy beams is proposed in this paper. A Dammann grating and an optimized splitting grating are superimposed, respectively, with an Airy cubic phase pattern to generate an array of 4×4 equal-space Airy beams. By adding a deflection grating to the superimposed phase patterns, the transverse self-accelerated Airy beams array can be deflected arbitrarily in two-dimensional plane. The impacts of superimposed phase patterns on the transverse acceleration and size of main lobe of Airy beams in array are discussed in this paper. Meanwhile, the accuracy of the steering method and the impact of the phase modulation depth on the size of the Airy beams are introduced.
