ACOUSTIC SIGNALS FOR MINE DETECTION
In late 1990s, a Buffalo physicist proposed using shock waves to detect plastic land mines costing as little as $1. Years later, the idea remains a striking approach to a detection problem that defeats metal detectorsPlastic land mines are difficult to find because metal detectors may miss them entirely. Researchers at the University at Buffalo explored ...- In 1997, Sandia won $393,000 to make fingerprints and other organic evidence blink under flashing light.
