People like to keep a safe distance from explosive substances, but in order to analyze them, close contact is usually inevitable. A new method has now been developed to detect chemicals inside a container over a distance of more than a hundred meters. Laser light is scattered in a very specific way by different substances. Using this light, the contents of a nontransparent container can be analyzed without opening it.
