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

Explore compact piezo phase shifter ideal for fast, precise optics and interferometry phase control. Read more.

They've cracked the code to determine the SM of a scattering medium embedded with quadratic nonlinearity. Their method, using a 256x256 SM dimension, emerges from four-phase interferometry.

PI, a global leader in piezo nanopositioning and precision motion control equipment, announces the S-312 piezo phase shifter stage series with five aperture diameters ranging from Ø2" (53mm) to Ø12" ...

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