The OSIRIS-REx Thermal Emission Spectrometer (OTES) Instrument
Space Science Reviews, 2018Co-Authors: Philip R. Christensen, Greg L. Mehall, Saadat Anwar, V. E. Hamilton, D. Pelham, W. O’donnell, H. Bowles, S. Chase, J. Fahlgren, Z. FarkasAbstract:The OSIRIS-REx Thermal Emission Spectrometer (OTES) will provide remote measurements of mineralogy and thermophysical properties of Bennu to map its surface, help select the OSIRIS-REx sampling site, and investigate the Yarkovsky effect. OTES is a Fourier Transform spectrometer covering the spectral range 5.71–100 μm ( 1750 – 100 cm − 1 $1750\mbox{--}100~\mbox{cm}^{-1}$ ) with a spectral Sample Interval of 8.66 cm − 1 $8.66~\mbox{cm}^{-1}$ and a 6.5-mrad field of view. The OTES telescope is a 15.2-cm diameter Cassegrain telescope that feeds a flat-plate Michelson moving mirror mounted on a linear voice-coil motor assembly. A single uncooled deuterated l -alanine doped triglycine sulfate (DLATGS) pyroelectric detector is used to Sample the interferogram every two seconds. Redundant ∼0.855 μm laser diodes are used in a metrology interferometer to provide precise moving mirror control and IR sampling at 772 Hz. The beamsplitter is a 38-mm diameter, 1-mm thick chemical vapor deposited diamond with an antireflection microstructure to minimize surface reflection. An internal calibration cone blackbody target provides radiometric calibration. The radiometric precision in a single spectrum is ≤ 2.2 × 10 − 8 W cm − 2 sr − 1 / cm − 1 $\leq2.2 \times 10^{-8}~\mbox{W}\,\mbox{cm}^{-2}\,\mbox{sr} ^{-1}/\mbox{cm}^{-1}$ between 300 and 1350 cm − 1 $1350~\mbox{cm}^{-1}$ . The absolute integrated radiance error is < 1 % $

Miniature Thermal Emission Spectrometer for the Mars Exploration
2003Co-Authors: Philip R. Christensen, Greg L. Mehall, Steven H. Silverman, Saadat Anwar, Noel Gorelick, Rolph Kheen, Tom Tourville, Duane Bates, Steven Ferry, Teresa FortunaAbstract:The Miniature Thermal Emission Spectrometer (Mini-TES) will provide remote measurements of mineralogy and thermophysical properties of the scene surrounding the Mars Exploration Rovers, and guide the Rovers to key targets for detailed in situ measurements by other Rover experiments. The specific scientific objectives of the Mini-TES investigation are to: (1) determine the mineralogy of rocks and soils; (2) determine the thermophysical properties of selected soil patches; and (3) determine the temperature profile, dust and water-ice opacity, and water vapor abundance in the lower atmospheric boundary layer. The Mini-TES is a Fourier Transform Spectrometer covering the spectral range 5-29 µm (339.50 to 1997.06 cm-1) with a spectral Sample Interval of 9.99 cm-1. The Mini-TES telescope is a 6.35-cm diameter Cassegrain telescope that feeds a flat-plate Michelson moving mirror mounted on a voice-coil motor assembly. A single deuterated triglycine sulfate (DTGS) uncooled pyroelectric detector with proven space heritage gives a spatial resolution of 20 mrad; an actuated field stop can reduce the field of view to 8 mrad. Mini-TES is mounted within the Rover’s War
