Abstract
Disclosed herein are devices and methods to provide a holographic optical element (HOE) having a modified shape and a structural attribute. At least one wavefront may be used to cause a first structure change in a material, used for the HOE, in a first shape. The material used for the HOE may be changed from the first shape to the modified shape to cause a second structure change in the material. The structural attribute in the material may be provided from a combination of the first structure change and the second structure change.
Claims25
A method to manufacture a holographic optical element (HOE), the method comprising:
- impinging at least one wavefront on a material having a first shape, the at least one wavefront to cause a first structure change in the material;
- shaping the material to a second shape to cause a second structure change in the material;
- and
- forming a holographic optical element (HOE), the HOE comprising the material having the second shape and a structural attribute, the structural attribute based in part on a combination of the first structure change and the second structure change.
A method to design a holographic optical element (HOE), the method comprising:
- simulating, via a digital computer, a holographic optical element (HOE), the HOE comprising a material having a modified shape and a structural attribute;
- simulating, via the digital computer, a wavefront to cause a first structure change in the material while the material is in a first shape;
- and
- simulating, via the digital computer, the material changing from the first shape to the modified shape to cause a second structure change in the material, the structural attribute in the material based in part on a combination of the first structure change and the second structure change.
At least one non-transitory machine-readable storage medium comprising instructions that when executed by a computing device, cause the computing device to:
- simulate a holographic optical element (HOE), the HOE comprising a material having a modified shape and a structural attribute;
- simulate a wavefront to cause a first structure change in the material while the material is in a first shape;
- and
- simulate the material changing from the first shape to the modified shape to cause a second structure change in the material, the structural attribute in the material based in part on a combination of the first structure change and the second structure change.
A holographic optical element (HOE), comprising:
- a shaped material having a structural attribute, the shaped material having the structural attribute provided by:
- impinging at least one wavefront on a material having a first shape, the at least one wavefront to cause a first structure change in the material;
- and
- shaping the material to a second shape to cause a second structure change in the material, the structural attribute based in part on a combination of the first structure change and the second structure change.
