Chemicals absorb light in different narrow spectral bands in a unique manner, creating a spectrum that can be used to indicate the presence of a chemical, identify the chemical, and quantify the concentration. Infrared systems for remote chemical detection use these spectral signatures to remotely detect, identify, and characterize chemicals in the gas or vapor phase. This technology is relatively new, only recently becoming mature enough for emergency responder use.
