One of the most perspective technique fabrications of diffractive optical elements (DOE) is circle raster scanning technique. The technique is implemented using laser writing system such as CLWS-300. In this paper, we propose a method of error characterization and correction of the angular coordinate to improve the accuracy of writing for polar coordinate writing system

    Β© 2020, Pleiades Publishing, Inc. Abstract: We present the results of the first year of searching for polar candidates within the 3BS (3-Band Survey) program using medium-band filters. Observational data for 84 selected objects from the catalog of cataclysmic variables of the CRTS DR1 sky survey were obtained while implementing the program. A dwarf nova during its outburst and a polar were detected. The available archival data are analyzed. The dwarf nova is of the U Gem or Z Cam type and contains a massive secondary component with M2 = 0.94 Β± 0.04 Mʘ. For the polar found we have estimated the orbital period PO = 0d.054437 and calculated the magnetic field strength of the white dwarf B β‰ˆ 32 MG
