Temporal Variations of the Turbulence Profiles at the Sayan Solar Observatory Site
Atmosphere, 2019 The paper focuses on the development of the method to estimate the mean characteristics of the atmospheric turbulence. Using an approach based on the shape of the energy spectrum of atmospheric turbulence over a wide range of spatial and temporal scales,

SPIE Proceedings, 2000 The SOFIA telescope as the heart of the observatory is a major technological challenge. I present an overview on the astro-nomical and scientific requirements for such a big airborne observatory and demonstrate the impact of these requirements on the layout of SOFIA, in particular on the telescope design as it is now.

Active optics: deformable mirrors with a minimum number of actuators [PDF]
Journal of the European Optical Society-Rapid Publications, 2012 We present two concepts of deformable mirror to compensate for first order optical aberrations. Deformation systems are designed using both elasticity theory and Finite Element Analysis in order to minimize the number of actuators.
