OTES is a Fourier-transform interferometer that collects hyperspectral thermal infrared data over the spectral range from 1750 to 100 cm–1 (5.7 to greater than 100 μm) with a spectral sampling of 8.66 cm–1 and a 6.5-mrad full-width, half-maximum (FWHM) instantaneous field of view (IFOV) in a single detector.

Christensen et al., 2017 describes the OTES instrument and detector calibrations in depth. In short, OTES collects 1350 ±3 double-sided interferogram samples. In order to have a consistent spectral sampling accounting for any sampling change over the life of the mission, the interferogram is filled with zeros to a uniform length of 1360 samples prior to performing the discrete Fourier transform. This number of samples, together with the measured laser wavelength of 0.849 μm resulting in a spectral sampling of 8.66 cm.
