Abstract:
1. An optical reflection device comprising: a flexible substrate extending in a first, longitudinal direction so as to have a first longitudinal end and a second longitudinal end longitudinally opposite to the first longitudinal end, the second longitudinal end being movable with respect to the first longitudinal end; a first elastic portion connected with the second longitudinal end of the flexible substrate; an optical reflector coupled with the flexible substrate via the first elastic portion; a first electrode layer provided on the flexible substrate; a piezoelectric layer provided on the first electrode layer; and a second electrode layer provided on the piezoelectric layer; wherein the optical reflector is arranged to swing about an axis extending in a second, lateral direction perpendicular to the first, longitudinal direction; and wherein the first elastic portion has a zigzag shape that proceeds in the second, lateral direction from the second longitudinal end of the flexible substrate to the optical reflector so as to connect laterally between the second longitudinal end of the flexible substrate and the optical reflector, the zigzag shape of the first elastic portion including plural longitudinally-extending portions extending toward the first longitudinal end of the flexible substrate.
