This quantum radar could image buried objects
The glass cell that serves as the radar’s quantum component is full of cesium atoms kept at room temperature. The researchers use lasers to get...
The world’s biggest space-based radar will measure Earth’s forests from orbit
These indirect systems rely on a combination of field sampling—foresters roaming among the trees to measure their height and diameter—and remote sensing technologies like lidar...
