title: Phase grid-type interferential spectrometer for the near infrared.
abstract: For studying the spectrum of weak extended sources in the 1-2-microm wavelength region, a phase grid-type interferential spectrometer was made. Its principle consists of decoding by a phase grid a Fourier interferogram localized out of an appropriated plane-wave interferometer. Its description (resolving power is approximately 30,000), a comparison with other interferential spectrometers, and first experimental results are given.
