Liquid Crystal Based Adaptive Optics System: Software v1.0 Final Report for Project: Wavefront Sensing for Liquid Crystal Adaptive Optics.

Abstract

This report results from a contract tasking The University of Durham as follows: The contractor will develop and test software to perform the following tasks: (a) interface with a Dalsa CCD Camera in order to read data from a Shack-Hartmann lenslet array. (b) Calculate the centroid positions of an 8x8 array of sp rom a Shack-Hartmann sensor. (c) Calculate the local wavefront gradients from the centroid positions. (d) Use the data from c) to reconstruct the Zernike coefficients for the wavefront. (e) Calculate the phase shifts to be applied t exagonal array of 127 pixels. (f) Convert the phase shifts into the voltages that are necessary to actuate the liquid crystal spatial light modulator.
