Optical system design and integration of the mercury laser altimeter

Appl Opt. 2005 Mar 20;44(9):1748-60. doi: 10.1364/ao.44.001748.

Abstract

The Mercury Laser Altimeter (MLA), developed for the 2004 MESSENGER mission to Mercury, is designed to measure the planet's topography by laser ranging. A description of the MLA optical system and its measured optical performance during instrument-level and spacecraft-level integration and testing are presented.
