Recent Examples of interferometer from the Web
The instrument is carefully calibrated so that, in the absence of a gravitational wave, the interference of the laser results in nearly perfect cancellation – no light comes out of the interferometer.
The LIGO observatories in Louisiana and Washington state, run by Caltech and MIT, are laser interferometers, experiments designed to pick up interference in light waves.
The interferometer then combines the beams, analyzes their light waves, and translates the resulting data into a digital image.
