Light Detection and Ranging Instrument (LIDAR)

NSSDCA ID: 2014-076A-04

Mission Name: Hayabusa2

Description

The Light Detection and Ranging Instrument (LIDAR) measures the time-of-flight of a laser pulse reflected from the surface of asteroid 162173 Ryugu to determine the surface topography. The LIDAR uses a 1064-nm yttrium-aluminum-garnet-Nd with Cr co-dopant (YAG-Nd + Cr) laser. The instrument has two receiver optics, near and far. The near receiver is designed for ranges < 1 km and has field of view of 1.5 mrad. The far receiver is designed for ranges > 1 km and has a field of view of 20.4 mrad, which yields a footprint size of 30 m in diameter at an altitude of 20 km, which is the ""home position"" of the Hayabusa2 spacecraft.
