Piezo Ceramic Fast Steering Mirror (PCFSM) is widely used in satellite laser communication, adaptive optical imaging and high-precision laser pointing due to its high resolution, precision and fast response.
Traditional PCFSM solutions are voice coil motor driven and piezoelectric ceramic driven. Voice coil motor driven PCFSM has large stroke, low driving voltage and high load capacity but is prone to environmental temperature and magnetic field interference, resulting in lower frequency response compared to piezoelectric ceramic driven PCFSM
Piezoelectric ceramic driven PCFSM offers small size, large driving force, high resolution and fast response but lacks impact resistance and exhibits non-linear properties such as dielectric relaxation and creep. To mitigate these effects, closed-loop feedback is used for calibration to ensure pointing accuracy.
Strain gauge, also known as resistive displacement sensor, is widely applied in piezoelectric ceramic precision driving devices due to its high resolution, good frequency response, small size, simple structure and ease of integration. Strain gauges are typically attached to the surface of piezoelectric ceramics to measure extensional displacement for closed-loop control.
PCFSM requires high-performance systems with high bandwidth, linearity and stability, posing higher demands on controllers.
