Solve the problems of the current measuring device 

1. There are certain requirements for measurement materials
2. Contact measurement, damage to the measurement material
3. The measurement range is small, the position is uncertain, and the measurement is difficult
4. The measurement speed is slow, the precision is low, and the measurement error is large

5. Complex structure and high cost
