 (ĭn′tər-fə-rŏm′ĭ-tər)
n.
Any of several optical, acoustic, or radio-frequency instruments that use interference phenomena between a reference wave and an experimental wave or between two parts of an experimental wave to determine wavelengths and wave velocities, measure very small distances and thicknesses, and calculate indices of refraction.

(ˌɪntəfəˈrɒmɪtə)
n
1. (General Physics) physics any acoustic, optical, or microwave instrument that uses interference patterns or fringes to make accurate measurements of wavelength, wave velocity, distance, etc
2. (Astronomy) astronomy a radio or optical array consisting of two or more telescopes separated by a known distance and connected so that the radiation from a source in space undergoes interference, enabling the source to be imaged or the position of the source to be accurately determined

in•ter•fer•om•e•ter

(ˌɪn tər fəˈrɒm ɪ tər)

n.
1. a device that splits light into two or more beams, usu. by reflection, and then brings them together to produce interference, used to measure wavelength, index of refraction, and astronomical distances.
2. an optical instrument for measuring the angular separation of double stars or the diameter of giant stars by means of the interference phenomena of light they emit.

Their data are combined interferometrically to create radio images with the sensitivity of a single 130-m dish, but with much higher spatial resolution.
For the analysis visualized in Figure 1, only a subset of 5 images between 23rd February - 12th April 2015 were combined interferometrically within a redundant connections network.
Because the device will work interferometrically, very small movements may be detected even with low-reflectivity surfaces.
