Electrostatic drive mirror apparatus

摘要

Disclosed herein is an electrostatic drive mirror apparatus including: electrostatic drive mirrors to be variably operated by electrostatic drive; an electrostatic mirror drive section formed on one semiconductor substrate, including at least mirror drive electrodes for driving the electrostatic drive mirrors and signal wirings for applying drive voltage on the mirror drive electrodes; a variable voltage source for supplying voltage from an external source to the electrostatic mirror drive section; drive switches for controlling and driving applied voltages from the variable voltage source to the electrostatic mirror drive section; holding capacitors for retaining the applied voltage to the electrostatic mirror drive section; and a control section for controlling at least the drive switches and the variable voltage source.
