NEW OPTICAL TECHNIQUES FOR THE 'STRUVE' SPACE ASTROMETRIC PROJECT
YERSHOV V. N.,TSUKANOVA G. I.,STARICHENKOVA V. D.,ZAKHARENKOV G. F.,GRIAZNOV G. M. The Korean Astronomical Society 1996 Journal of The Korean Astronomical Society Vol.29 No.suppl1
A few optical schemes for the future Russian astrometric satellite ('Struve') are discussed. New optical materials and techniques developed at the Vavilov State Optical Institute are planned to be used for the on-board telescopes. Optical characteristics of the reflecting Schmidt and a three - mirror scheme for the on-board telescopes are compared.
A SCANNING CCD DETECTOR FOR SOLAR ECLIPSE OBSERVATIONS
YERSHOV V. N. The Korean Astronomical Society 1996 Journal of The Korean Astronomical Society Vol.29 No.suppl1
A wide-field CCD detector for solar eclipse observations is discussed. The CCD is supposed to be of a moderate size, and the image of the corona is obtained by scanning the field of view. Results of the 1995 solar eclipse observation are shown which have been made with a prototype of the scanning CCD detector.
SUB-MILLIARCSECOND ACCURACY WITH THE STRUVE ASTROMETRIC SATELLITE
YERSHOV V. N. The Korean Astronomical Society 1996 Journal of The Korean Astronomical Society Vol.29 No.suppl1
The Struve astrometric satellite which is being developed at Pulkovo Observatory in cooperation with Krasno-yarsk Institute of Applied Mechanics, S.I. Vavilov's State Optical Institute and some others space instrumentation institutes, will produce observations of a second epoch for the Hipparcos stars. The project is devoted to maintaining the Hipparcos coordinate system as well as extending it to a density of $\approx$ 100 stars per square degree. Possibilities of submilliarcsecond accuracy of observations with single aperture on-board telescopes are discussed. Requirements to the optical scheme and to the dynamic properties of the spacecraft are formulated. CCD and microchannel plates are discussed as a focal assembly detectors.

This article analyzes the state and development of multimedia technologies in the educational process. The reasons for the emergence of multimedia educational technologies are shown. The definition of the concept of "multimedia education" is given. The advantages and disadvantages of teaching using multimedia technologies are presented. The article, based on multimedia technologies, provides one of the ways to solve the problem of lack of classroom time for the presentation of all educational material in the process of teaching engineering students. The creation and application of educational videos in education is discussed, an example of teaching electrical engineering is given; the requirements for the development of video lessons, their advantages and importance in the educational process are indicated.
