- W2013856744 abstract "Conformal optical domes are characterized as having external more elongated optical surfaces that are optimized tominimize drag, increased missile velocity and extended operational range. The outer surface of the conformal domestypically deviate greatly from spherical surface descriptions, so the inherent asymmetry of conformal surfaces leads tovariations in the aberration content presented to the optical sensor as it is gimbaled across the field of regard, whichdegrades the sensor's ability to properly image targets of interest and then undermine the overall system performance.Consequently, the aerodynamic advantages of conformal domes cannot be realized in practical systems unless thedynamic aberration correction techniques are developed to restore adequate optical imaging capabilities. Up to now,many optical correction solutions have been researched in conformal optical design, including static aberrationscorrections and dynamic aberrations corrections. There are three parts in this paper. Firstly, the combination of static anddynamic aberration correction is introduced. A system for correcting optical aberration created by a conformal dome hasan outer surface and an inner surface. The optimization of the inner surface is regard as the static aberration correction;moreover, a deformable mirror is placed at the position of the secondary mirror in the two-mirror all reflective imagingsystem, which is the dynamic aberration correction. Secondly, the using of appropriate surface types is very important inconformal dome design. Better performing optical systems can result from surface types with adequate degrees offreedom to describe the proper corrector shape. Two surface types and the methods of using them are described,including Zernike polynomial surfaces used in correct elements and user-defined surfaces used in deformable mirror(DM). Finally, the Adaptive optics (AO) correction is presented. In order to correct the dynamical residual aberration inconformal optical design, the SPGD optimization algorithm is operated at each zoom position to calculate the optimizedsurface shape of the MEMS DM. The communication between MATLAB and Code V established via ActiveX techniqueis applied in simulation analysis." @default.
