Three-Dimensional Imaging Laser Radar: Development and Applications

Speaker: Dr. Rick Heinrichs , MIT Lincoln Lab
Date: September 26 2002
Time: 4:00pm
Location: NE43-941

Lincoln Laboratory has been developing technologies to enable three-dimensional (3-D) imaging laser radar. These include sensor arrays, which integrate single-photon-sensitive detectors with high-timing-precision CMOS counters, and short-pulse, high-efficiency, solid-state laser illuminators. These technologies have been integrated into several laser radar systems that have been used to make measurements of a variety of targets and scenes under different conditions. Except for data loss due to line-of-sight shadowing, a 3-D image of a target is orientation independent and can be viewed at any angle. This offers a unique ability for target segmentation and recognition. 3-D images also provide the ability to "see through" obscurants such as foliage, clouds, and camouflage by range gating out the part of the return from the obscuring medium.

The presentation will first discuss the present state of the technology development for 3-D laser radar as well as the advantages of the Lincoln approach. Selected 3-D images and movies will be presented along with a discussion of several applications of the technology.
