Vision and interferometry improve calibration of large monolithic mirrors
In a new study published in Measurement, researchers from the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences have developed a calibration method that combines machine vision with interferometry. This method separates a mirror's fixed internal offset from changes in the test path alignment.
We haven't written up this one. Phys.org has the full story — the link below goes straight to it.
