Ultra-Compact, High-Resolution LADAR System for 3D Imaging

An eye-safe LADAR system weighs under 500 grams and has range resolution of 1 mm at 10 m. This laser uses an adjustable, tiny microelectromechanical system (MEMS) mirror that was made in SiWave to sweep laser frequency. The size of the laser device is small (70×50×13 mm). The LADAR uses all the mature fiber-optic telecommunication technologies in the system, making this innovation an efficient performer. The tiny size and light weight makes the system useful for commercial and industrial applications including surface damage inspections, range measurements, and 3D imaging.

This work was done by Jing Xu and Roman Gutierrez of SiWave, Inc. for NASA’s Johnson Space Center. For further information, contact the JSC Innovation Partnerships Office at (281) 483-3809.
