The system consists of a home-made Shack\u2013Hartmann wavefront sensor and silver-coated bimorph deformable mirror operating in a closed-loop control scheme. The wavefront sensor used an uncooled vapor phase deposition PbSe focal-plane array for the actual light sensing. An effect of thermal afterimage was found to be reducing the centroid detection precision significantly. The effect was analyzed in detail and finally has been dealt with by updating the background calibration. System stability was increased by reduction of control modes. The system functionality and stability were demonstrated by improved focal spot quality. By replacing some of the used optics, the range of the demonstrated mid-IR AOS could be extended to cover the spectral range of 1\u20135 \u00b5m. To the best of the authors&#8217; knowledge, it is the first AO system built specifically for mid-IR laser wavefront correction.<\/p>\n","oddelovace":"none"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v23.9 -
