Compact high-resolution echelle-AOTF NIR spectrometer for atmospheric measurements

, 2017
A new concept of a high-resolution near-IR spectrometer consisting of an echelle grating combined with an acousto-optic tunable filter (AOTF) for separation of diffraction orders, is developed for space-borne studies of planetary atmospheres.

Differential FeI Line Shifts as Convective Signatures in R=40,000 ' Echelle Spectra?

, 2007
. The convection in stellar atmospheres cause spectral lines to be more or less blue-shifted. The differential wavelength shift between two groups of spectral lines could be used to characterize the convection.
