Paper Abstract

In this talk we will present a new zonal wavefront sensor. The device is able to take a single incident beam and diffract it into multiple beams with different focal locations, according to the presence and strength of particular aberrations. The Zernike terms in the beam are simply read out according to the location of the foci on the image plane CCD. We have created a hologram design such that the locations of the beams can be quickly and easily determined, providing all necessary information to correct for these aberrations, so that the wavefront information is derived without the need for any computations. It is a very compact and practical device that could potentially have applications for the USAF airborne laser or atmospheric distortion characterization.
