MOLA PRECISION RADIOMETRY DATA
RECORD
Description
The Mars Orbiter Laser Altimeter
not only provides surface topography from the laser pulse
time-of-flight, but also two radiometric measurements, the active
measurement of transmitted and reflected laser pulse energy, and the
passive measurement of reflected solar illumination. The passive
radiometry measurement is accomplished in a novel fashion by
monitoring the noise density at the output of the photodetector and
solving for the amount of background light. The passive radiometry
measurements provide images of Mars at 1064-nm wavelength over a 2 nm
bandwidth with sub-km spatial resolution and with 2% or better
precision under full illumination.
