A New Linear Optical Differentiation Wavefront Sensor for Laser Tomography on ELTs
Abstract
We present a new concept for an optical differentiation wavefront sensor, providing a very high number of phase measurements in the pupil, and featuring a linear response versus the phase gradient. The principle is described, and the functionning is illustrated through a few examples obtained in laboratory.
