  1. Construction: Accurate representations of building and interiors in vivid detail can be used by architects and designers to create and view virtual 3D images of the projects they plan to build.
  2. Oil and gas: Differential Absorption LiDAR (DIAL) is a method of oil and gas exploration. In addition to being used to detect gas and particles, LiDAR mapping also provides an accurate 3D model of the terrain, minimizing the project’s environmental impact. This could be a beneficial tool used in oil rigs around the world.
  3. Law enforcement: Historically, fingerprint detection has been achieved using chemical reagents, such as ninhydrin or diazafluorenone. With LiDAR integrated smart glasses, fingerprints could be visualized in 3D through use of infrared lasers. This would eliminate chemicals, dusting and subsequent laboratory analysis, enabling law enforcement to scan and match fingerprints at a crime scene in a matter of seconds.
