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.
Claims17
An image generating device for obtaining an image of an object, comprising:
- a control module configured to generate a first signal having a first frequency component and a first phase component for a first axis direction, and a second signal having a second frequency component and a second phase component for a second axis direction;
- an emitting unit configured to emit light to the object using the first signal and the second signal;
- and
- a light receiving unit configured to obtain light receiving signal based on returned light from the object;
- wherein the control module is configured to obtain a first data set based on the first signal, the second signal and the light receiving signal,
- wherein the control module is configured to obtain a second data set based on the first data set by adjusting at least one of the first phase component of the first signal and the second phase component of the second signal,
- wherein the control module is configured to select from the first data set and the second data set based on predetermined criteria, and
- wherein the image of the object is generated based on the selected data set.
An Image generating method for obtaining an image of an object, comprising:
- generating a first signal having a first frequency component and a first phase component for a first axis direction, and a second signal having a second frequency component and a second phase component in a second axis direction through a control module;
- obtaining light receiving signal based on returned light from the object, through a light receiving unit;
- obtaining a first data set based on the first signal, the second signal and the light receiving signal,
- obtaining a second data set based on the first data set by adjusting at least one of the first phase component of the first signal and the second phase component of the second signal
- selecting from the first data set and the second data set based on predetermined criteria,
- generating the image of the object based on the selected data set.
