As the development of space technologies, the human beings want to send vehicles to land on Mars instead of doing observations by far. Future robotics and human exploration vehicles to the planetary will require safe and precision landing. Lidar is one of the most effective sensors for Hazard Avoidance and Autonomous Landing. A 3-D imaging Lidar was designed in this paper. The Lidar uses a linear detector array and a 2-D galvanometer scanner and can get a 3-D image of 30 deg*30 deg within 0.1 second. This paper will discuss the design and application of the Lidar itself. Test results show that it can achieve 0.2 meter horizontal resolution and 0.1meter vertical accuracy.
