SELECTED APPLICATIONS OF LIDAR
Architectural Documentation
Lidar structured-light scans documented the interior and exterior of the
Philipse Manor Hall in Yonkers, NY. The interior scan shown produced
three-dimensional images of this colonial-period building. The resulting
three-dimensional models document the architectural elements as a
means of preservation and understanding. For instance, a model of the
18th-century Rocco decorative papier-mâché ceiling in one room was
used to produce molds for replicas in a restoration project.

Flight Altimeter
Perseverance rover and Ingenuity helicopter landed on Mars
in 2021 (artist's concept). The powered, controlled flight of
Ingenuity was a first on another planet. It was accomplished
using a LIDAR-Lite-V3 module as an altimeter. This Garmin
technology provided three-centimeter accuracy at a 50-Hz
sampling rate in the extreme environment of Mars.

Mine Dust Monitor
A Lidar-based, portable monitor (left image) was
developed to detect air quality for mine safety, i.e.,
detection of potential hazardous airborne particulate
matter. This prototype was an undergraduate design
project of Z. Osterwisch, A. Mauntel, N. Nisbett, and
D. Barua with supervision of Dr. Ahmad Alsharoa at
Missouri S&T. A dust plume (right image) is imaged
and can provide information on plume location,
particle size, and particle concentration.

Autonomous Vehicle
Lidar technology can provide information on the environment for
autonomous vehicles. Moving and stationary objects throughout the
surrounding three-dimensional space must be detected with Lidar in
conjunction with other technologies, e.g., cameras. Simulations are used
to understand and develop Lidar systems. A traffic simulation using
ANSYS simulation software is shown.
