The degree of freedom of movement is multi-dimensional, and the optical motor changes from single-axis focusing to multi-axis movement. With more functions, optical image stabilization has gradually become popular.
Accuracy and speed are improved, from open loop to closed loop. The focus is faster and the anti-shake effect is better.
The thrust becomes larger and the power consumption becomes lower. It is mainly driven by the electromagnetic drive of the voice coil motor, and becomes the coexistence of multiple drive modes such as memory metal, piezoelectric motor, electrostatic motor, etc.
