Inverse problems in astronomical adaptive optics

摘要: Adaptive optics (AO) is a technology used in ground-based astronomy to correct for the wavefront aberrations and loss of image quality caused by atmospheric turbulence. Provided some difficult technical problems can be overcome, AO will enable future astronomers achieve nearly diffraction-limited performance with extremely large telescopes that are currently under development, thereby greatly improving spatial resolution, spectral resolution observing efficiency which achieved. The goal this topical review present inverse community representative sample these problems. In review, we first tutorial overview mathematical models techniques current systems. We then examine detail following topics: laser guidestar adaptive optics, multi-conjugate multi-object high-contrast imaging deformable mirror modeling parameter identification.
