Abstract

Aberrations produced by transparent optical elements and random scatterers in a focused laser beam are corrected by measuring the phase and then imprinting the phase conjugate onto the beam. The field is represented with a Hadamard basis and the phase contributions of each element are measured with interferometry. We investigate implementing the basis on a Bessel beam, which is projected into a ring and can result in a reduction of the number of elements needed in the basis to get a reasonable correction.
