Figure 1: Schematic layout of a White-light Interferometer. A CCD image sensor like those used for digital photography is placed at the point where the two images are superimposed. A broadband “white light” source is used to illuminate the test and reference surfaces. A condenser lens collimates the light from the broadband light source.
A white light scanner (WLS) is a device for performing surface height measurements of an object using coherence scanning interferometry with spectrally-broadband, "white light" illumination. Different configurations of scanning interferometer may be used to measure macroscopic objects with surface profiles measuring in the centimeter range, to ...

Zygo Corporation, or simply Zygo, is a manufacturer headquartered at Middlefield, Connecticut, that specializes in optical systems and equipment.Their metrology product lines include 3D measuring microscopes using coherence scanning interferometry, laser Fizeau interferometers for testing optical components, laser displacement interferometers, and heterodyne optical encoders for stage position ...
Optical coherence tomography (OCT) is an imaging technique that uses interferometry with short-coherence-length light to obtain micrometer-level depth resolution and uses transverse scanning of the light beam to form two- and three-dimensional images from light reflected from within biological tissue or other scattering media.
"President Biden got it absolutely wrong and created a lot of pain here in Northeastern Pennsylvania," Gov. Josh Shapiro said after President Joe Biden's commutation of a judge in Pennsylvania's ...
Coherence scanning interferometry (CSI) is any of a class of optical surface measurement methods wherein the localization of interference fringes during a scan of optical path length provides a means to determine surface characteristics such as topography, transparent film structure, and optical properties.
The only person to win the White House on a second try as the party nominee was Richard Nixon, another California senator turned vice president who first tried retrenching with a gubernatorial run ...
