Summary
Phase-space tomography reconstructs focused x-ray beams, separating optical aberrations from the original field. This method accurately measures both the field and system aberrations for advanced optics research.
Area of Science:
- Optics and photonics
- X-ray imaging and optics
Background:
- Compound refractive lenses are crucial for focusing X-rays.
- Characterizing X-ray beam properties, including aberrations, is essential for high-resolution imaging.
