REMOTE SENSOR AND IN-SITU SENSOR SYSTEM FOR IMPROVED DETECTION OF CHEMICALS IN THE ATMOSPHERE

摘要

A system having an optical remote sensor where sensing can be achieved from distance, and therefore without necessarily making contact with the threat chemical, with one or more in-situ sensors where sampling of air is required, and where at least one sensor is cross-reactive. Aspects of some of the various systems capable of achieving, but not limited to thereto, the following advantages: (a) by the optical sensor: long range advanced warning, rapid large volume analysis, fast response continuous monitoring for protection against bursts, safety to the operator, (b) by the in-situ sensor: high sensitivity, (c) by the combination of sensors, high specificity, better avoidance of interferences by chemicals and (d) by the inclusion of cross reactive characteristics, the ability to learn response to new chemicals.
