Image generating device

An optical device, comprising:

• an optical fiber having a fixed end and a free end;
• a first actuator positioned at an 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,
• wherein the first rod position and the second rod position of the optical fiber are positioned between the actuator position and the free end,
• wherein the deformable rod is substantially parallel to the optical fiber from the first rod position of the optical fiber to the second rod position of the optical fiber, and
• wherein, in the cross section perpendicular to the longitudinal axis of the optical fiber, the deformable rod is arranged such that an angle between a virtual line connected from the first end of the deformable rod to the first rod position of the optical fiber and the first direction is within a predetermined angle,
• whereby the movement of the optical fiber in a second direction perpendicular to the first direction is limited when the free end of the optical fiber moves in the first direction as the first actuator applies the first force on the actuator position of the optical fiber.
