Abstract
An optical device may include a lens system. The optical device may include a first scanning component to receive an optical beam and to scan the lens system with the optical beam. The optical device may include a second scanning component to receive the optical beam from the lens system and to scan a field of view with the optical beam, where the lens system is positioned between the first scanning component and the second scanning component. The lens system may include a beam expander.
Claims20
An optical device, comprising:
- a first scanning component configured to receive an optical beam along an optical axis;
- a second scanning component spaced apart from the first scanning component along the optical axis;
- and
- a lens system positioned between the first scanning component and the second scanning component,
- wherein the lens system is configured to:
- receive the optical beam from the first scanning component,
- change a collimated beam size of the optical beam, and
- refract the optical beam to prevent an angular offset of the optical beam from translating into a spatial offset of the optical beam on the second scanning component.

An optical device, comprising:
- a first scanning component configured to receive an optical beam along an optical axis,
- wherein the first scanning component is configured to tilt around an axis to create an angular offset of the optical beam relative to the optical axis;
- a second scanning component spaced apart from the first scanning component along the optical axis,
- wherein the second scanning component is configured to tilt around the axis;
- and
- a lens system positioned between the first scanning component and the second scanning component,
- wherein the lens system is configured to:
- receive the optical beam from the first scanning component,
- increase a collimated beam size of the optical beam, and
- refract the optical beam to prevent an angular offset of the optical beam from translating into a spatial offset of the optical beam on the second scanning component.
