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

Fringe conference can be traced to the automatic processing of fringe patterns. The term “patterns” evokes an image of flowing lines elegantly wrapped around surface contours. However, automatic ...

Laser interferometry has emerged as a leading non‐contact method for the precision measurement of gear geometries. By utilising the interference of coherent light, these systems can detect minute ...

A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest ...

It is useful for expanding the effective aperture of the interferometer, in one axis. The measurement area is around the same size as the beam when a laser interferometer's round measurement beam ...

Accurately controlling film thickness and uniformity is extremely important for both throughput and performance in the automotive, aerospace, semiconductor, medical, and research industries. White ...

All periodic signals can be described in terms of amplitude and phase. We all learned that in basic circuit theory. You surely recall having to calculate signal’s phase change when it passed through a ...
