Title:
LIGHT DEFLECTOR
Document Type and Number:
WIPO Patent Application WO/2023/281993
Kind Code:
A1
Abstract:
A first piezoelectric actuator (3) includes a first piezoelectric cantilever part (32) that is driven in a resonant state by a piezoelectric element (31a) provided between a torsion bar (5) and an inner frame (6). A second piezoelectric actuator (4) includes a second piezoelectric cantilever part (34) that is driven in a non-resonant state by a piezoelectric element (31c) provided between the inner frame (6) and an outer frame (7). The inner frame (6) has an at least partially curved shape between the first piezoelectric cantilever part (32) and the second piezoelectric cantilever part (34). The second piezoelectric cantilever part (34) has an at least partially curved shape along the curved shape of the inner frame (6).
