Fiber optic fire sensor
The recent growth in the use of fiber optics for communication and data transmission has made this technology readily available for other applications. The combination of optical fibers, infrared detection, and signal processing with an embedded microcontroller has resulted in a flame detector with significant advantages over previous types. While previous active fiber optic sensors depended on filter breakage during a fire, this type is a passive sensor. Sensitivity in detecting small fires and the ability to avoid response to non-fires are improved over similar usage non-fiber optic sensors. Performance of the sensor in cluttered areas and optical multiplexing to reduce the number of electronic modules are discussed. Advantages of the sensor are large field of view, EMI immunity, operation in high temperature environments, and detection in dirty, hard to reach areas. Commercial applications include large storage areas, electrical generating equipment installations, and other hazardous industrial environments where combustibles are present. Results of fire detection tests in an aircraft engine nacelle are discussed.
