Abstract:
LIDAR (LIght Detection And Ranging) that measures distance by the laser
pulse is a necessary sensor of navigation for a deep space explorer that
a deep space exploration that doses a planetary exploration. Two dimension
of LIDAR scanning is required from both sides of the navigation control and
the science observation in order to make a 3D map of surface efficiently.
This paper proposes a novel method on the beam scanning mechanism for a receiver
telescope with big aperture by using MEMS technology. In addition, it reports
on the result of executing the basic function experiment of the beam scanning
mechanism.
The scanning optics system is composed by a telecentric telescope, and a micro
shutter array. This optical system has achieved a narrow viewing angle
corresponding to aperture of the shutter by limiting the view of the telescope
that has a wide viewing angle with the shutter.
We experimented by using the shutter array of 6mm×6mm size. As a result, it
succeeded about the scanning angle in the achievement of azimuth angle 8.8deg,
elevation angle 8.1deg, and the field of view angle of azimuth angle 1.8deg and
elevation angle 0.6deg.
