The UAV launches straight up from the deck of the USS Midway, its operator carefully maneuvering it in front of the ship’s air traffic control tower. Along its predetermined flight path, the UAV captures lidar measurements and IR imagery for a few minutes before descending back to its landing pad. Dan Jennings, of the Naval Information Warfare Center (NIWC) Pacific, operates a commercial off-the-shelf UAV outfitted with a corrosion/anomaly detection sensor payload and processing scheme. He's aboard the USS Midway Museum in San Diego during a demonstration of the Office of Naval...Read full article

    lidar
    Lidar, short for light detection and ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects and surfaces. Lidar systems typically consist of a laser scanner, a GPS receiver, and an inertial measurement unit (IMU), all integrated into a single system. Here is how lidar works: Laser emission: A laser emits laser pulses, often in the form of rapid and repetitive laser...
    infrared
    Infrared (IR) refers to the region of the electromagnetic spectrum with wavelengths longer than those of visible light, but shorter than those of microwaves. The infrared spectrum spans wavelengths roughly between 700 nanometers (nm) and 1 millimeter (mm). It is divided into three main subcategories: Near-infrared (NIR): Wavelengths from approximately 700 nm to 1.4 micrometers (µm). Near-infrared light is often used in telecommunications, as well as in various imaging and sensing...
