Extended Field of View using Multi Conjugated Deformable Lenses

Aberration correction in an optical system is a critical step in optical design. Nowadays optical design can be consideredd optically perfect and most of the cases where we face aberration or imagedegradation this is due to external causes such as refractive index inhomogeneities of the sample in the case of microscopy, thermal aberrations in the case oh high power beam lasers or air turbulence in the case of astronomy or optical communications. One of the main tool for aberrations correction is Adaptive Optics (AO) that by using a multi actuator deformable mirror in its standard configuration can correct for pupil aberrations. There are some cases however where the aberrations are field dependent. This led to the Multi Conjugated Adaptive Optics (MCAO) implementation where multiple deformable mirrors are used. This configuration tough highly increase system complexity, so in my thesis work I studied for the first time the use of deformable lenses as a replacement for deformable mirrors in the case of a MCAO setup in microscopy or atmospheric turbulence correction.
