General Description
The Chemical Agent Line Sensor (CALS) detects and identifies releases of chemical warfare agents (CWAs) and toxic industrial agents (TICs) over a line path. The system can be used by several types of large open-volume facilities to determine whether a covert chemical release is occurring. It was specifically designed for low maintenance, no consumables, low cost, rapid deployment, and high detection performance to fit a wide array of facility constraints.
Technical Description
The CALS system is an open path Fourier Transform Infrared (FTIR) chemical sensor. The system transmits Long Wave Infrared (LWIR) energy from a filament to a spectrometer spatially partitioned from the transmitter. The amount of absorbance at each wavelength is measured and used to identify the amount and type of agent present between the transmitter and receiver.
Notes:
Not to be confused with the DoD's Common Analytical Laboratory System (CALS) which shares the same acronym.
