Induced aberrations by combinative convex/concave interfaces of refractive-index-mismatch and capability of adaptive optics correction

摘要: Adjustable fluidic adaptive lenses have been extensively studied because of the advantage changing geometric shape or refractive index without any mechanical moving parts. However, induced aberrations were rarely discussed before. We address this issue by first clarifying experimentally due to injected volumes. Experimental results show that under volume 0.1 ml, main come from Z1 (piston), Z2 (tip), and Z5 (defocus) Zernike coefficients are 0.97, 0.31, 1.31 μm, respectively. In what follows, a series tests specifically designed explore convex/concave interfaces refractive-index-mismatch (RIM). Furthermore, we demonstrate capability optics (AO) correction on combinative effects multiple layers with RIM. A microelectro-mechanical system (MEMS) deformable mirror (DM) 140 actuators was used in conjunction Shack–Hartmann wavefront sensor realize experimentation. particular, consider aberration introduced RIM between water/oil glass. After AO correction, can improve root mean square (RMS) 2.17–0.17 μm for an interface water As oil glass, capable improving RMS 0.24–0.10 μm. © 2011 Wiley Periodicals, Inc.
