Paper Abstract

We introduce a modal wave front sensing technique of using binary computer generated hologram (BCGH) and a coding approach. Several types of Zernike aberrations were encoded into the BCGH using this method. Light wave front was modulated by BCGH and single Zernike aberration mode respectively, and the holographic modal wavefront sensor was simulated and verified. The results show that, wave front distorted by a special aberration mode, after modulated by the BCGH, can be transformed into beams which have a relative intensity, which can reflect the change trend of the aberration coefficients in the unknown wavefront.
