As the illegal drug trade continues to plague communities around the world, law enforcement and security personnel face an ongoing challenge in identifying concealed narcotics. Contraband such as cocaine, heroin, and methamphetamines can be easily obscured from traditional detection methods. Thankfully, new scanning technologies are giving authorities a powerful advantage in the fight against dangerous drugs.
Near-Infrared Spectroscopy
One of the most promising Narcotics Scanner for narcotics detection is near-infrared spectroscopy. This non-destructive analytical technique uses the near-infrared region of the electromagnetic spectrum, with wavelengths from about 750 nm to 2500 nm. When near-infrared light interacts with matter, it excites molecular vibrations and rotations in chemical bonds. Each chemical compound has a unique molecular structure and bonding that determines how it will interact with and absorb near-infrared light.
By analyzing the spectral signature of light absorbed, reflected, scattered, or transmitted, near-infrared spectroscopy can identify the presence and concentration of target substances even when mixed with other materials. This allows scanners to peer inside packages, vehicles, cargo containers, and more to detect microscopic traces of illegal drugs without opening sealed containers. For security checkpoints, portable handheld systems have been developed for quick scans of luggage, mail, and other items.
