Phase-Shifting Interferometry (PSI) techniques have become fundamental in optical metrology for accurately measuring surface topographies and reconstructing three‐dimensional profiles.

In astronomy, larger distances are both a blessing and a curse. They can cause issues like longer communication times, which ...
