Title:
OPTICAL REFLECTION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2010/058565
Kind Code:
A1
Abstract:
Provided is an optical reflection element including a mirror portion and an oscillator coupled to the mirror portion. The oscillator includes: a base, an insulation layer formed on the base; a drive element and a monitor element which are formed separately from each other by a separating groove on the insulation layer. Each of the drive element and the monitor element is formed on the insulation layer by successively layering a lower electrode layer, a piezoelectric layer, and an upper electrode layer. This improves the detection accuracy of the monitor element and realizes self-excited driving of the optical reflection element with a high accuracy.
