Ամփոփում:

In this paper we present the innovative Polarization-Holographic Imaging Stokes Polarimeter which is developed based on a unique polarization-holographic diffraction element and allows one to determine full polarization of a light coming from a point or an extended space object in visual and near-infrared spectral ranges. Laboratory tests and first astronomical polarimetric observations show that the resulting errors are of the 10−4 order. As an example, the preliminary results of the polarimetric observations of some bright Algol-type variable stars and spicules are presented.

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
