We propose an approach of a focal plane imaging device for a telescope, which is based on spatially-scanned solitary photodetector, and can be used as an alternative to matrix detectors (CMOS or CCD). This approach allows to set efficient sensor size, pixel resolution, sensitivity and recording time on customer demand. Technical feasibility of up to 200 pixel/mm (5000 ppi) spatial resolution for focal field of up to astronomical photographic plate size, with the detection noise- equivalent power of 3 x 10-15 W/√ Hz and the measurement time of ≈ 1 minute per megapixel is justified.

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.
