Uncontrolled releases of chemical pollutants represent a major threat for public health and security. Their detection, identification and release point localization constitute a real challenge to health, security and first responder’s communities. One promising detection method is based on imaging passive standoff detection and identification of chemical vapors. To investigate this method, Defense Research and Development Canada (DRDC) – Valcartier developed and tested passive Long Wave Infrared (LWIR) hyperspectral imaging (HSI) sensors for standoff detection. The initial effort was focused to address the standoff detection and identification of toxic industrial chemicals (TICs) and precursors. Sensors such as the Improved Compact ATmospheric Sounding Interferometer (iCATSI) were developed for this application. This paper describes the sensor developments and presents results of standoff detection and identification of chemical pollutants. The standoff sensor is based on differential Fouriertransform infrared (FTIR) radiometric technology and is able to detect, spectrally resolve and identify small plumes at kilometer’s ranges. Results from a series of field trials in several typical scenarios will be presented. These results will serve to establish the potential of the method for standoff detection of pollutants and surrogates.
