Optical device with adjustable optical surface

摘要

An adjustable optical device (10) comprising at least a deformable optical surface (20) activated by linear fluidic actuators comprising:
- a material layer (100) comprising an upper surface (110) on which the optical surface (20) is provided and a bottom surface (130, 140);
- an actuator layer (200) comprising a plurality of linear fluidic actuators separated by at least one cavity (250), where at least one linear fluidic actuator is a pillar (205) extending in the actuation direction (L) which is non parallel to the bottom surface (130, 140) of the material layer (100), said pillar (205) comprising a wall (220) delimiting an internal cavity (210) and where an upper surface (240) of said pillar (205) is continuously linked to a zone (130) of the bottom surface of the material layer (100);
- fluidic inlets suitable for introducing a fluid in at least one internal cavity (210) of a pillar lineal fluidic actuator (205).
