Abstract

This paper reports the results of some experiments on wavefront sensing at La Palma, Canary Is., using a Shack-Hartmann sensor. From the Shack-Hartmann data, we derive estimates of the seeing parameter r₀ and compare different methods of wavefront reconstruction: a new method of wave front reconstruction based on Bayes' theorem is presented. The design of a Shack-Hartmann sensor for operation at 2 micrometers on UKIRT is described.
