Problems solved by technology

The problem with this solution is that it needs to use a large area of ​​optical fiber encoding technology, which makes the two-dimensional position detection method complicated.

The problem with this solution is that multiple small-sized scintillators are coupled with position-sensitive photodetectors, and the resolution of two-dimensional position detection depends on the size of the scintillator, resulting in low position resolution of two-dimensional position detection.
