The Chang'E 1 laser altimeter is the first laser instrument in lunar orbit made in China. It has one beam and operates at 1 Hz, with a nominal accuracy of 5 m. The laser altimeter has been operating successfully on lunar orbit since its operation on 28 November 2007. It has acquired over nine millions data sets on lunar altitude. This chapter describes the principle of the laser altimeter, the design of instrument, the emission unit, receiving unit, test of the laser altimeter and its application in orbit.
