Introduction: Interferometer uses ac laser as light source and thus used to measure large distance ,the laser beam wavelength is exact and pure for highly accurate measurements. Astronomers have linked the two 10-m (33-ft) optical telescopes in these domes on Mauna Kea, Hawaii to make what is effectively a single, much more powerful telescope. Additional Products Although its original form used incoherent white light, it is now usually realized using a laser. In order to generate an interference pattern with high precision (distinct fringes), it is very important to have a single highly stable wavelength source, which is achieved using the XL-80 laser.. Astronomers also use interferometers to combine signals from telescopes so they In practice, everyday laboratory constraints sometimes make that kind of precision hard to achieve. 2015 Apr 6;23(7):9121-9. doi: 10.1364/OE.23.009121. Destructive interference means waves subtracting and canceling out. The laser beam is split into two parts. Keysight's laser interferometry products are available as standard systems or are fully configurable to meet individual application requirements.
