D. A. Yagnatinskii, V. N. Fedoseev Luch Research and Production Association, Podol’sk Abstract: We present a novel numerical and analytical method for calculating the influence functions of actuators of a rectangular deformable mirror with free edges in a model of concentrated loads. The deflection function of a mirror is found as a Fourier series in… Read More »
A. V. Korobtsov, S. P. Kotova, N. N. Losevskii, A. M. Maiorova, S. A. Samagin Samara Branch of P. N. Lebedev Physical Institute, Russian Academy of Sciences Abstract: The feasibilities of an annular optothermal trap to capture and manipulate transparent micron-sized objects are studied experimentally and simulated numerically. Compared to point optothermal traps, an annular… Read More »
R. V. Romashko, M. N. Bezruk, Yu. N. Kulchin Institute for Automation and Control Processes, Far Eastern Branch of the Russian Academy of Sciences, Vladivostok Far Eastern Federal University, Vladivostok Abstract: We propose a novel scheme of a polarisation-independent (PI) adaptive interferometer based on orthogonal geometry of vectorial two-wave mixing in a gyrotropic photorefractive crystal.… Read More »
E. P. Pozhidaev, S. P. Kotova, S. A. Samagin P. N. Lebedev Physical Institute of the Russian Academy of Sciences, Moscow Samara Branch of P. N. Lebedev Physical Institute, Russian Academy of Sciences Abstract: We study the possibility of using a ferrielectric liquid crystal as an electro-optical medium for phase spatial light modulators. Electro-optical characteristics… Read More »

Lebedev Physical Institute of the Russian Academy of Sciences, Moscow HoloGrate, Joint-Stock Company, St. Peterburg Abstract: An imaging (stigmatic) spectrograph composed of a flat grazing-incidence VLS grating and a focusing broadband normal-incidence multilayer mirror (Mo/Be, 111–138 Å Mo/Si,… Read More »
V. V. Liger, V. R. Mironenko, Yu. A. Kuritsyn, M. A. Bol’shov Institute of Spectroscopy, Russian Academy of Sciences, Troitsk, Moscow Abstract: A new version of diode laser absorption spectroscopy (DLAS) is developed for determining the temperature of hot zones. The technique is based on a combination of slow scanning of the radiation frequency of… Read More »
