PASCO interferometer setup (a component box containing 10 different optical components and an optical base with built-in micrometers), a HeNe laser with alignment bench, tungsten This creates a disruption of space-time that spreads far from its point of emergence and at a speed close to that of light. A complex system of mirrors brings the light from the separate telescopes to the astronomical instruments where it is then processed in order to re-create a high quality, finely detailed image. While one light beam interacts with the object being measured, the other does not, and their constructive interference results in a pattern or spatial shape that can then be used for extremely accurate and complex measurements.

As seen in Fig. The applications are directed at improving target discrimination and identification; improving transportability for forwarddeployment and reducing the cost of MDA radars. Interferometry applications at different wavelength such as 1319 nm or 532 nm are also possible. The possibility of laboratory applications also seem remote, in particular the idea that intensity interferometry could be used at x-ray wavelengths to measure the phase of scattering amplitudes is shown to be ruled out by inadequate sensitivity which could only be overcome by the development of coherent x-ray sources. Interferometry is an imaging technique in which waves are superimposed in a manner to cause interference.
