FAST does 'eye exercises' to maintain top performance

"The chief engineer, Jiang Peng, proposed that a safety assessment system must be built for the super reflector," said Li Hui, an engineer responsible for the structure during debugging.

Then, the team applies the integrated simulation of whole process technology to completely digitize the entire reflector through a mechanical model to show the influence on the telescope inserted by bugs during observation. Alarms go off automatically when it's beyond its limits.
