Distributed Chemical Sensor
The first Distributed Chemical Agent Sensing and Transmission (DiCAST®) system was installed at a regional airport facility in June 2005. This initial DiCAST® installation is providing a continuous line of protection in key segments of the facility against a high-priority military chemical agent and a toxic industrial chemical. DiCAST® integrates stable and sensitive reagents for rapid chemical detection within the plastic cladding of specially designed and drawn optical fibers. The sensing fibers respond to the presence of a toxic chemical in seconds, at concentrations less than 10% of the most common acute health effects regulatory limit.
