Space-time Wavefront Analysis Using a Coordinate Remapping Shack-Hartmann Sensor

Abstract

In this project, we wished to make the first measurements of the spatial-temporal characteristics of wavefronts in the infrared by taking advantage of the exisiting infrared camera (IRCAM3) and fast controller (ALICE) [1] at the 3.8m United Kingdom Infrared Telescope (UKIRT). The intention was to have a system that could eventually be used for routine measurements as part of the UK’s Joint Observatories Site Evaluation (JOSE) campaign: a re-engineered version of the system described here has in fact now been constructed for the JOSE programme.
