Classification: CPC G  H | IPC G

Claim 18:
19. The system of claim 1, wherein the dynamic gain control comprises:
a first buffer that captures the slow-scan drive signal;
a second buffer that captures the inner loop feedback signal;
a comparator that compare one or more characteristics of the captured slow-scan drive signal and the captured inner loop feedback signal; and
a gain adjustor comprising:
a PID controller that receives a detected difference from the comparator and the target gain; and
a gain controller that receives an output from the PID controller, wherein the gain controller is configured to adjust the gain of the inner control loop responsive to the output from the PID controller such that the slow-scan feedback signal is gain scaled by the adjusted gain to provide the inner loop feedback signal.
