I definitely would like an English translation. Though, from what I understand (the diagram and the translation of the title) it's a graphic input device that can work out a few points at the time, and not in the same sphere (as echos will overlap, a point I develop in my article).
So it's not properly able to scan an object like I did?
Apart from that, how have you found that untranslated 1975 Russian patent? Google Scholar?
It's impressive what they were able to build with such low-tech.
