| Abstract: | The wavefront corrector is one of the key parts of an adaptive optical system.It is difficult to fabricate and is easy to damage if an improper voltage is applied.The overvoltage damage mechanism for the wavefront corrector is described and a scheme for avoiding overvoltage damage of the wavefront corrector with voltage dividing network is proposed.The implementation of an overvoltage protective circuit based on programmable ASIC is introduced.The testing shows that the circuit has achieved a satisfied result. |
