Abstract

• This work conducted with atmospheric turbulence in mind i.e. astronomical/satellite imaging • We have developed a computer model of a Shack-Hartmann sensor incorporating shot and ccd read noise with three main aims - • 1. To establish the optimal (pupil plane equivalent) Hartmann sub-aperture size for a given signal-noise scenario. • 2. To explore possible benefits of Bayesian wavefront estimation when operating at low light levels. • 3. To investigate improved slope estimation techniques.
