| Abstract | Imaging and other scientific instruments in space can reveal mysteries of the universe that reach far beyond any distance that would ever be practical for human space travel. As far back as the 1600s, Galileo used the crudest possible telescope technology to see the largest moons of Jupiter. The secret to making telescopes better is to make their apertures (that is, their mirrors that collect the light) bigger. The bigger the aperture, the farther the telescope can see, and the bigger the aperture, the fainter the objects it can see. One very practical way to make huge telescope apertures is to use a technique called interferometry. Interferometry is the science of mixing light captured by two or more telescopes. This article explains how interferometry works and discusses topics such as: vector inspectors; disturbance and anti-disturbance; and adding dimension and precision. (ERIC). |
