Optical Flame Detection System and Method

Optical Flame Detection System and Method

Docket: UAH-P16012

Technology

In recent years, billions of dollars have been spent on forest and other open area fire protection. Open area fires cause extensive property and eco-damage annually, but existing flame detectors have not found widespread use due to their limited range of detection and lack of reporting systems.

Researchers at UAH have developed an optical flame detection method that collects and concentrates flame-specific energy into its detection apparatus, while rejecting false alarms due to solar radiation. When fashioned in an array and installed at certain heights, these detectors can sense flames for 360 degrees at long ranges.

The flame detector is sensitive to the ultraviolet C radiation range emitted by open flames, while ignoring the UV A and B radiation ranges emitted by the sun. This design makes it possible for the detector to operate in daylight without the risk of false triggers from solar radiation.
