Abstract
A system and method for correcting optical aberrations in optical devices, such as wide-field microscopes, optical tweezers and optical media devices, such as DVD drives. The system uses adaptive optics to correct optical aberrations, such as spherical and space-variant aberrations. Spherical aberrations can be corrected using one adaptive optical elements and space-variant aberrations can be corrected using numerous adaptive optical elements in tandem. The adaptive optical elements may be of several types, such as a liquid lenses, deformable membrane mirrors or various liquid crystal phase and amplitude modulators. Adaptive optics can also be used to simultaneously shift the focus of the optical device and correct optical aberrations.
