Explosives detection is a field of research that focuses on developing technologies and methods to identify and detect explosive materials in various contexts, such as security screening at airports, transportation facilities, and military checkpoints. Researchers in this area study the physical and chemical properties of explosives, as well as the behaviors and characteristics that can be used to differentiate them from other materials. The goal of explosives detection research is to enhance the capabilities of security personnel and law enforcement agencies in detecting and preventing explosive threats, ultimately improving public safety and national security. Techniques employed in this field include imaging technologies, trace detection methods, and spectroscopy.
