Abstract
In some implementations, an optical device may include a first optical element, wherein the first optical element is a first prism. The optical device may include a second optical element, wherein the second optical element is a second prism, and wherein the optical device is configured to receive a beam and output the beam. The first optical element and the second optical element may be configured to alter a beam shape of the beam, such that the beam has a first shape at a first location and a second shape at a second location.

An optical device, comprising:
- a first optical element,
- wherein the first optical element is a first pyramidal prism having three facets and a base;
- and
- a second optical element,
- wherein the second optical element is a second pyramidal prism having three facets and a base,
- wherein the optical device is configured to receive a beam and output the beam, the first optical element and the second optical element being configured to alter a beam shape of the beam, such that the beam has a first shape at a first location and a second shape at a second location,
- wherein the optical device is configured to split the beam into a plurality of components at the first location, and
- wherein at least one of the first optical element or the second optical element is movable to adjust the second shape.
An optical system, comprising:
- a collimating lens to collimate a beam;
- a focusing lens to focus the beam;
- and
- an optical device to shape the beam, the optical device being disposed between the collimating lens and the focusing lens, the optical device comprising:
- a first pyramidal prism having three facets and a base, and
- a second pyramidal prism having three facets and a base,
- the first pyramidal prism and the second pyramidal prism being positioned to cause the beam to have a first beam shape in a near-field and a second beam shape in a far-field,
- the first pyramidal prism is configured to split the beam into a plurality of components, and
- at least one of the first pyramidal prism or the second pyramidal prism is movable to cause the second beam shape in the far-field.
A method, comprising:
- setting, by a controller, a relative position of a first optical element and a second optical element within an optical device within an optical system to a first relative position,
- wherein the first optical element and the second optical element are a pair of pyramidal prisms each having three facets and a base,
- wherein the optical system outputs a beam with a first beam shape with the relative position set to the first relative position,
- wherein the optical device is configured to receive the beam and output the beam, the first optical element and the second optical element being configured to alter a beam shape of the beam, such that the beam has the first beam shape at a first location and a second beam shape at a second location,
- wherein the first optical element is configured to split the beam into a plurality of components at the first location, and
- wherein at least one of the first optical element or the second optical element is movable to adjust the second beam shape;
- and
- adjusting, by the controller, the relative position of the first optical element and the second optical element within the optical device within the optical system to a second relative position,
- wherein the optical system outputs the beam with the second beam shape with the relative position set to the second relative position.
