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.
Figure 2. File:Twyman-Green interferometer set up as a white light scanner. Vertical scanning interferometry is an example of low-coherence interferometry, which exploits the low coherence of white light. Interference will only be achieved when the path length delays of the interferometer are matched within the coherence time of the light source.
Optical coherence tomogram of a fingertip. It is possible to observe the sweat glands, having "corkscrew appearance" Interferometric reflectometry of biological tissue, especially of the human eye using short-coherence-length light (also referred to as partially-coherent, low-coherence, or broadband, broad-spectrum, or white light) was investigated in parallel by multiple groups worldwide ...
Shearing interferometer (lateral and radial) Twyman–Green interferometer; Talbot–Lau interferometer; Watson interferometer (microscopy) White-light interferometer (see also Optical coherence tomography, White light interferometry, and Coherence Scanning Interferometry) White-light scatterplate interferometer (white-light) (microscopy)
Michelson interferometers using a white light source White light has a tiny coherence length and is difficult to use in a Michelson (or Mach–Zehnder ) interferometer. Even a narrowband (or "quasi-monochromatic") spectral source requires careful attention to issues of chromatic dispersion when used to illuminate an interferometer.
In a new court filing, federal prosecutors allege the suspect who took a hostage and got into a shootout with Yellowstone National Park rangers in July ranted that he "refuse[s] to fraternize with ...

Her spirit, too, is one that kids can relate to. “She's always kind, but she's a child,” Marja says. “She makes mistakes, but she also addresses them.
