  • valguslainete interferentsil põhinev lainepikkuse ja murdumisnäitajate mõõteriist
  • instrument in which an acoustic, optical, or microwave interference pattern of fringes is formed and used to make precision measurements, mainly of wavelength
    Good to know
    • Interferometers are widely used in science and industry for the measurement of small displacements, refractive index changes and surface irregularities. See also: interferometry (related) [ IATE:1485237 ]

Usage examples
  • Tuntuim on Michelsoni interferomeeter, selle abil lahutatakse ühest valgusallikast lähtuv valguskiir poolläbipaistva peegli abil kaheks ristsihiliseks kiireks.
interferometer
Usage examples
  • Typically in an interferometer, a wave is split into two parts, which travel different paths and the waves are then combined to create interference. When the paths differ by an even number of half-wavelengths, the superposed waves are in phase and constructive interference is observed, increasing the amplitude of the output wave. When they differ by an odd number of half-wavelengths, the combined waves are 180° out of phase and destructive interference is observed, decreasing the amplitude of the output. Anything that changes the phase of one of the beams by only 180° shifts the interference from a maximum to a minimum.
