Invention:
This technology is a novel way of printing diffractive pupils through a means of maskless lithography on any surface.
Background:
Currently, the fabrication of diffractive pupils is limited to planar surfaces because there are many issues and restrictions with printing diffractive pupils on aspheric mirror surfaces. Printing diffractive structures on a spherical mirror is an inconvenient method currently and causes asymmetric distortion in telescopes.
Applications:
- Printing of diffractive pupils
- Clearer imaging
- Precision and accuracy of exoplanets
Advantages:
- Not limited to binary structures, rotational or planar surfaces
- Reduces cost and weight
- Expands the field-of-view
- Occurrence of asymmetric pupils become impossible
- Reduces asymmetric distortion
