Requirements for dynamic characteristics of adaptive optics systems

V. P. Lukin V.E. Zuev Institute of Atmospheric Optics, Siberian Branch of the Russian Academy of Science, Tomsk Abstract: Dynamic characteristics of adaptive optics systems operating with radiation transmitted through a turbulent atmosphere are analysed on the basis of analytical calculations of the Strehl ratio using the theory of optical wave propagation in randomly inhomogeneous… Read More »

Optimisation of light focusing by mesowave Fresnel phase plates with tilted zone profiles

Yu. E. Geints, E. K. Panina V.E. Zuev Institute of Atmospheric Optics, Siberian Branch of the Russian Academy of Science, Tomsk Abstract: We present the results of numerical simulation of optical radiation focusing by a phase Fresnel zone plate (ZP) of mesowave size with zones having an inclined profile. In order to reveal the features… Read More »
