Paper Abstract

A novel form of Shack-Hartmann wavefront sensor is described which can be used in existing infrared and visible cameras with only minimal disturbance to their optics. Such a device has been installed in IRCAM3, the common-user IR camera on UKIRT (United Kingdom Infrared Telescope). The camera's fast readout electronics and a purpose built data storage system allows the wavefront slopes to be measured in 25 sub-apertures at frame rates of between 30 and 100 per second. The first spatially and temporally resolved IR wavefront measurements are presented and an outline is given of the use of this wavefront sensor for long term monitoring on both Mauna Kea, Hawaii and La Palma, Canary Islands.
