LARGE AZIMUTHAL TELESCOPE
Zverev Victor Alexeevich
39
The history of development of the Large Azimuthal Telescope is presented. Basic features of the telescope design are described.
SPACEBORNE OPTICAL-DIGITAL SYSTEMS AND COMPLEXES
Demin Anatoly V., Alexander V. Denisov , Alexander V. Letunovsky
51
Tendencies of the progress in main lines of development of optical-digital systems for remote sensing of the Earth from the space are reviewed on the base of public data.
MODERN E-SCIENCE SOFTWARE PACKAGES FOR COMPUTER MODELING
Boukhanovsky Alexander V, Vladimir N. Vasiliev
60
Basic features of modern software packages for computer modeling in the frames of e-Science paradigm are considered. The packages architecture, specifics of installation on a computation platform, dataware characteristics, implementation, and life cycle support are described.
INVESTIGATION OF A SIGNAL PROCESSING METHOD FOR HIGH-SPEED OPTICAL
COHERENT TOMOGRAPHY SYSTEMS
Elena A. Vorobyeva, Gurov Igor P, Maxim V. Peterson
65
Method of asynchronous signal amplitude demodulation in optical coherent tomography is considered. The method is based on successive execution of quadratic transformation of informational component of the interferometric signal and low-pass filtering. Error in signal envelope restoration with the use of sub-discretization and decimation of signal readings is estimated with the account for additive noise effect. Examples are presented of signal envelope restoration with the use of Butterwort low-pass filter for useful signal detection in optical coherent tomography.
APPLICATION OF NANOIMPRINT LITHOGRAPHY TO MANUFACTURE NANO- AND
MICROELEMENTS IN PHOTONICS
Арефьева Н. Н., Denisyuk Igor Yu.
74
Manufacturing of polymer micro-optical elements by contact duplication with the use of flexible stamp is considered. The effect of shrinkage of UV-hardened composition on duplication accuracy is studied experimentally. Possibility of nano-sized structure duplication with existing equipment is confirmed by experiment with 1800 Grooves/mm diffraction grating.
KINEMATIC AND DYNAMIC PARAMETERS OF AUTOMOBILE MOVEMENT
Pavel A. Dmitriev, Musalimov Victor M
78
Dynamics of plane movement of an automobile is considered. Parameters are defined that make it possible to monitor the movement with the use of velocity and acceleration sensors.
THERMOPHYSICAL ASPECTS OF FLUIDIZATION IN GENERATING UNIT
Дульнев Г. Н., Pilipenko Nikolay V., Maria A. Khodorchenko
83
Significance of thermal measurements for exploration of dynamics of fluidization processes in modern generating technologies. Basic methods and instruments to measure thermal and structural hydrodynamic parameters of the systems are described.
