What is the classification of scanning galvanometer

 Scanning galvanometer classification - drive mode: 

 1. Analog Scanning galvanometer: 

 Advantages: inexpensive and commonly used 

 Disadvantages: poor immunity to interference 

 2. Digital Scanning galvanometer: 

 Advantages: good stability, strong anti-interference ability, can be applied to complex electromagnetic environment 

 Cons: Higher price than analog galvanometer 

 Scanning galvanometer classification - positioning mode: 

 1. Optical galvanometer: 

 Advantages: small size and inexpensive 

 Disadvantages: poor positioning accuracy, poor anti-interference ability, slow response time 

 2. Grating galvanometer: 

 Advantages:  high positioning accuracy, fast response speed, anti-interference  ability is stronger than photoelectric galvanometer, 

 Can be used in highly sophisticated applications 

 Disadvantages: higher price than photoelectric galvanometer, slightly larger size
