measurement results
The membrane roughness Ra is about 0.8 μ m

Addressing the current issues with measuring devices

1. There are certain requirements for measuring materials
2. Contact measurement may cause damage to the measuring material
3. The measurement range is small, the position is uncertain, and the measurement is difficult
4. Slow measurement speed, low accuracy, and large measurement errors

5. Complex structure and high cost
