Vision and interferometry improve calibration of large monolithic mirrors
Phys.org ·
The Brief
- Researchers at the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences developed a calibration method combining machine vision with interferometry.
- The method is reported in a study published in the journal Measurement.
- The method separates a mirror's fixed (static) error from its dynamic error for large monolithic mirrors.
Why it matters
Accurate calibration of large monolithic mirrors matters for optical instruments such as telescopes, where surface errors limit image quality.
