A procedure of the nonlinear dispersion interferometry, that is virtually lacking limitation due to sensitivity, is proposed for the utility in absorption spectroscopy. The dispersion interferometer (DI) in the simplest form is comprised of two optical frequency doublers between which the object under study is placed. The DI method also gives a straightforward measurement of the dispersion part of refractive index of the studied medium. The major advanced feature of the DI is its insensitivity to vibrations, because their effect is decreased by a factor of approx.10 for quartz and approx.10 for air.
