Abstract

Wavefront analysis of an aberrated Laguerre-Gaussian beam generated using LC-SLM and after passing through a a Pseudo Random Phase Plate(PRPP) is carried out using Shack Hartmann wavefront sensor. The Zernike polynomials coefficient are calculated and compared with and without the L-G beam passing through a PRPP (mimicking atmospheric turbulence). It is found that the aberrations like piston and tilt have a greater value under the influence of turbulence.
