Three-Dimensional Imaging Laser Radar: Development and Applications
Speaker: Dr. Rick Heinrichs , MIT Lincoln Lab
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.
