Abstract

We propose a novel method for generating axial cosine structured light by using a phase-only spatial light modulator. The computer generates double concentric annular slits with different radii, and prism phase is applied on the slits so that the light beam incident on the slits is inclined away from the optical axis. The Bessel beams with different axial wave vectors generated by different annular beams, and the axial cosine structured light can be obtained from the interference between two Bessel beams. The period and phase of the axial cosine structured light can be adjusted by adjusting the radius and initial phase difference of the double concentric annular beam. We have proved theoretically and experimentally that this method can effectively generate axial cosine structured light.
