Amplitude-Modulated Sensors Could Save Pilots from Wire Hazards

Eliezer “Lazer” Besdin, Engineer

AM scanning laser rangefinder sensors could make less costly, lighter-weight systems for helicopter-mounted wire-warning systems. Wires represent a significant hazard for low-flying helicopters: Collisions with unobserved wire obstacles can result in helicopter or wire damage, or even injuries or fatalities. Because wires are long, thin objects, they may be difficult to detect against various backgrounds (Figure 1). Figure 1. These wires blend in with the background, becoming nearly invisible, and their length and thinness offer no clues as to how far away they are. Even if wire...Read full article

    laser rangefinder
    A laser rangefinder is a device that uses laser technology to measure the distance between the device and a target. It operates on the principle of measuring the time it takes for a laser beam to travel to the target and back, calculating the distance based on the speed of light. Laser rangefinders are commonly used in various applications, including surveying, hunting, golfing, military and defense, and outdoor activities. Key points about laser rangefinders: Distance measurement: The...
