Wave-front correction is a common technique used in optics and imaging to improve the quality of an optical system. It involves correcting aberrations and distortions in the wave-front of light that occur as it passes through various optical elements. This correction is typically done using adaptive optics systems that use deformable mirrors or liquid crystal arrays to adjust the wave-front of the light to compensate for these aberrations. By correcting for these distortions, wave-front correction can enhance the resolution and clarity of images obtained through optical systems, such as telescopes or microscopes.
