2. Today, images with very high resolution are obtained using interferometers.

3. They are also used in optical parametric oscillators and some interferometers.

4. Most interferometers use light or some other form of electromagnetic wave.

5. The present invention relates to interferometers (200-900) with adjustable path length differences (lags).

6. Large radio interferometers have been used to map the active jets emitted from active nuclei.

12. The success of this experiment was important in pushing ahead the construction of the Submillimeter Array and the Atacama Large Millimeter Array interferometers.

13. Images of hotspots on the surface of Betelgeuse taken at visible and infra-red wavelengths using high resolution ground-based interferometers Perrin, Guy; Malbet, Fabien (2003).

14. A fiber optic acoustic sensor array is based upon a Sagnac interferometer rather than being based upon Mach-Zehnder interferometers as in known acoustic sensor arrays.

15. The Biod MOX is a versatile screening workstation based on Increase Relative Optical Power (IROP) techonology, which relies on the interferometric optical signals of two interferometers as a biosensing method of quantifying the biomolecule accumulation or recognition in the sensing area.
