- Abstract
- [ABSTRACT ONLY] An experimental and numerical evaluation of a near infrared fire detector for indirect view monitoring is presented. The near infrared fire detector measures the spectral radiation intensitities incident on it at two wavelengths (900 nm and 1000 nm). These intensities are used to calculate a time series of apparent source temperatures. The fire detection algorithm utilizes the probability density function and the power spectral density of the apparent source temperatures to infer the presence of a fire.
