However, since the mechanical scanning is slow, it is difficult to make 3D images of moving tissues.
He went on to say, " Mechanical scanning will, in my opinion, be the most popular system.
The main advantage of the STAR architecture is that it requires no mechanical scanning of an antenna.
German propaganda claimed the system was superior to the British mechanical scanning system, but it never became operational.
Facsimile transmission systems for still photographs pioneered methods of mechanical scanning of images in the early 19th century.
After considerable effort, they decided this concept simply didn't work, and that the mechanical scanning systems were a better solution.
Unlike later examples, this used a mechanical scanning system, with two photocells examining changes in contrast as the seeker oscillated left and right.
Such an instrument can record a spectral function without mechanical scanning, although there may be tradeoffs in terms of resolution or sensitivity for instance.
Doherty also hinted that the technology might ultimately be applied more broadly in the office-copying market, where performance is now limited by mechanical scanning speeds.
Early TV systems, such as that of E . F . W . Alexanderson in the 1920s, used mechanical scanning and had a motor synchronized to the power system.
