background

● MEMS micro mirrors have been widely used for optical devices such as projectors and endoscopes
● Requirement for three-dimensional (3-D) scanning by MEMS micro mirror in addition to 1-D or 2-D scanning
● Increase in device size due to increase in driving direction

summary

● By single driving apparatus, MEMS micro mirror is actuated in  three resonant modes
● MEMS micro mirror is operated in 3-D by single superposed signal with the three resonant frequencies

predominance

● Miniaturization of whole device by single driving apparatus and single driving signal

application/development

● Optical device that acquires 3-D images such as an endoscope and retinal projector
