Instrument Overview
===================

The Diviner Lunar Radiometer Experiment is in most respects a copy 
of the Mars Climate Sounder (MCS) instrument on Mars Reconnaissance 
Orbiter.  Both instruments observe radiation with 21 detectors in 
each of nine spectral bands.  MCS is primarily an atmospheric limb 
sounder that measures temperature, pressure, water vapor, dust, and 
condensates at Mars' atmospheric limb.  In contrast, Diviner is a 
surface pushbroom mapper that measures emitted thermal radiation 
and reflected solar radiation from the surface of the moon. Two 
Diviner solar channels measure 0.3-3 micrometers reflected solar 
radiation.  Three Diviner channels near 8 micrometers classify 
regolith mineralogy by mapping the location of the Christiansen 
feature.  The remaining four Diviner channels measure surface 
temperature in four spectral bands ranging from 12.5 micrometers 
to beyond 200 micrometers.

Hardware Overview
=================

The Diviner Lunar Radiometer Experiment is a nine channel 
infrared radiometer employing filter radiometry. These channels 
are distributed between two identical, boresighted telescopes, 
and an articulated elevation/azimuth mount allows the telescopes 
to view the lunar surface, space, and calibration targets. The 
instantaneous field-of-view (FOV) response of each channel is 
defined by a linear, 21-element, thermopile detector array at 
the telescope focal plane, and its spectral response is defined 
by a focal plane bandpass filter.

The Diviner structure consists of an instrument optics bench 
assembly (OBA), an elevation/azimuth yoke, and an instrument 
mount. The OBA contains all of the instrument optical 
subassemblies, and is suspended from the yoke. Elevation and 
azimuth motors mounted on the yoke drive instrument articulation. 
The OBA can be temperature controlled, and internal temperature 
gradients are minimized by design. Radiometric calibration is 
provided by views of blackbody and solar targets mounted on the 
yoke. The electronics subassemblies control signal processing, 
instrument operation and articulation, command processing, and 
data processing.  These electronics are distributed between the 
OBA and the yoke.

bandpasses and functions, please see the EDR Software
Interface Specification (SIS).
