The resolving power of an optical system is often limited by the presence of timevarying wavefront distortions caused by heat flows. The aberrations do not only include tip/tilt and focus terms, but also higher spatial frequencies, due to the heat flow’s turbulent nature. TNO has built an adaptive optics (AO) breadboard, to demonstrate the correction of thermally induced wavefront aberrations using various control algorithms and a deformable mirror (DM) based on reluctance actuators [1].
