Seeing measurements with a Hartmann wavefront sensor

Open Access Open Access

Abstract

A fifty-five-element Hartmann wavefront sensor has been constructed using an array of lenses and an array of position sensing devices. Daytime measurements of ro (Fried’s seeing parameter), the wavefront tilt power spectrum, and the atmospheric phase structure function have been made by tracking the image motion of solar pores. Results are presented and compared to theoretical predictions.
