Photonics Spectra - October 2016

…interferometric metrology tools have become necessary
for today's modern optical fabrication. The
development of digital phase-shifting interferometry in around 1970 at Bell Labs was a
crucial innovation for optical fabrication.
Without this technology, the high-precision
