Abstract
An optical device may include an optical fiber having a fixed end and a free end; a first actuator positioned at a actuator position between the fixed end and the free end and configured to apply a first force on the actuator position of the optical fiber such that a movement of the free end of the optical fiber in a first direction is caused, wherein the first direction is orthogonal to a longitudinal axis of the optical fiber; and a deformable rod disposed adjacent to the optical fiber, and having a first end and a second end, wherein the first end is connected to a first rod position of the optical fiber and the second end is connected to a second rod position of the optical fiber.
Claims14
An optical device comprising:
- an optical fiber having a fixed end and a free end;
- a first actuator connected to the optical fiber at the fixed end of the optical fiber, the first actuator being configured to apply a first force on the optical fiber along a first axis direction, wherein the free end of the optical fiber is to move in a first direction in response to the first force;
- and
- a deformable rod spaced in parallel to the optical fiber, the deformable rod being attached to the optical fiber with at least one connector;
- wherein in response to the first force, the free end of the optical fiber is to move in a second direction different to the first direction in addition to moving in the first direction in accordance with an attachment angle of the deformable rod,
- wherein the attachment angle is an angle between the first axis direction and an attachment direction in a cross-section plane perpendicular to a longitudinal axis of the optical fiber,
- wherein the first axis direction is a direction of the first force projected to the cross-section plane,
- wherein the attachment direction is a direction from the optical fiber to the deformable rod in the cross-section plane, and
- wherein the deformable rod is attached to the optical fiber within an allowable angle range, the allowable angle range being determined to limit a movement of the free end in the second direction.
An optical device comprising:
- an optical fiber having a fixed end and a free end;
- an actuator module including at least one actuator, the actuator module being connected to the optical fiber at the fixed end of the optical fiber and configured to apply a force on the optical fiber to move the free end of the optical fiber;
- and
- a housing accommodating the optical fiber and the actuator module,
- wherein a mass having a predetermined size is attached to the optical fiber between the fixed end and the free end,
- wherein the mass is located within an anti-collision distance range adjacent to the free end of the optical fiber to prevent the mass from colliding with an inner wall of the housing when the optical fiber vibrates based on the force applied by the actuator module, and
- wherein the anti-collision distance range is determined by at least one of a maximum driving range of the optical fiber from a center of an inner diameter of the housing and a maximum driving range of the mass from the center of the inner diameter of the housing being less than a half of the inner diameter of the housing when the optical fiber vibrates.
