By product, the market has been segmented into swept-source optical coherence tomography (SSOCT)-based biometers, partial coherence interferometry (PCI)-based biometers, and optical low coherence reflectometry (OLCR)-based biometers.
Two-pion interferometry yields HBT radii that describe the geometry of these regions of homogeneity (regions that emit correlated pion pairs).
Figure 2 shows the designed flowchart to mitigate ionospheric error on SAR interferometry by using the azimuth offset method.
Basic techniques of satellite SAR interferometry (InSAR) have been applied using ERS and Envisat data (Lazecky et al., 2012), ALOS-1 (Lazecky et al., 2012; Lazecky and Jirankova, 2013; Kadlecik et al.
The IBM people had not designed an interferometer, of course, but their optical circuitry seemed sophisticated enough to be adaptable to interferometry. Duncan figured that the fast-growing photonics industry already had or would soon invent fabrication solutions that his suddenly imagined telescope could use.

For final film interpretation, the co-PET thickness values were compared with both the white light interferometry thickness values and the CFD co-PET flow values.
In the August 29th Science, they report distance results derived using very long baseline radio interferometry. They claim to have nailed the distance at 444.0 light-years, accurate to within 1%.
The typical camera-based interferometry includes different methods, such as photoelasticity [2], moire interferometry [3], electronic speckle pattern interferometry (ESPI) [4], shearography [5], digital holography [6], and white-light interferometry [7].
Radio Interferometry and Satellite Tracking provides a fine resource addressing the critical issue of space communications and satellites that are proliferating so much that they are causing overcrowded orbits - and it provides a fine understanding of radio interferometers for tracking and monitoring satellites in overcrowded conditions.
To calculate the slow rotation and to find the exact time, scientists have been using an extremely precise technique called Very Long Baseline Interferometry (VLBI).
"This three-telescope interferometry is a major milestone toward directly imaging the growth phase of supermassive black holes," said Sebastian Hoenig, a postdoctoral researcher at the UC Santa Barbara Department of Physics, and one of the astrophysicists who utilized this technique to observe the AGN at the centre of galaxy NGC 3783.
