Title:
MIRROE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/013271
Kind Code:
A1
Abstract:
A mirror control device is provided with a rotatably supported mirror (230),
electrodes (340a-340d) disposed apart from the mirror (230), a driving voltage
generating means (401) for generating a driving voltage for every electrode
in accordance with a desired slant angle of the mirror (230), a bias voltage generating
means (402) for generating a voltage for every electrode as a bias voltage to make
the slant angle of the mirror (230) the same defined value when a voltage is individually
applied to each of the electrodes (340a-340d), and an electrode voltage applying
means (403) for adding the bias voltage to the driving voltage for every electrode
and for applying the added voltage to its corresponding electrode (340a-340d).
