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

“Optical interferometry plays an essential role in precision metrology such as in gravitational wave detection, gyroscopes, and environmental sensing. Weak value amplification enables reaching the ...

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 ...

Manufacturing a precision surface requires a balance between satisfying the optimum quality requirements at the minimum cost. Steve Martinek summarizes the challenges of increasing the precision ...

This article outlines how to measure, control, and stabilize the relative distance of two interferometer paths to sub-wavelength precision over numerous wavelengths, using the Zurich Instruments MFLI ...

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 ...

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 ...
