FIELD: optics; instrument engineering.
SUBSTANCE: invention relates to optical instrument-making and concerns Michelson Interferometer with oscillating mirrors. Interferometer includes n mirrors, where n ≥ 2. Mirrors are made with possibility to provide Ω variable optical stroke difference in time by law of 
at oscillation frequency, where δxi=2Ai/cosθi is amplitude of oscillations of optical difference stroke from i-th mirror, which varies with amplitude Ai, phase shift φi and reflects light at angle of θi.
EFFECT: technical result consists in improvement of spectral resolution.
