Wavefront characterization for orbital angular momentum (OAM) modes is demonstrated using quadrature phase-shift interference. The phase fronts and intensity profiles of OAM(-2), OAM(-4), OAM(-6), and OAM(-8) are measured. Wavefront correlations between the experimental results and the pure Laguerre-Gaussian modes are calculated to evaluate the measurement.(More)
We present OAM mode distortion monitoring by using an interferometer with π/2 phase-shift to reconstruct the phase profile without any movement of instruments. Monitoring of distortion caused by misalignment and atmospheric turbulence are successfully demonstrated.
