Abstract
A system and method for detecting airborne agents. The system includes a semiconductor ultraviolet optical source configured to emit an ultraviolet light, a controller configured to generate a pseudo-random code for emission of the ultraviolet light modulated at the pseudo-random code, a telescope configured to focus the ultraviolet light to a distance from the source and to receive elastically backscattered signals and fluorescence signals from the distance, and a sensor configured to detect the elastically backscattered and fluorescence signals. The method generates a pseudo-random code and emits at least one wavelength of ultraviolet light modulated at the pseudo-random code, transmits the modulated ultraviolet light pulses to a distance from the source, receives elastically backscattered signals and fluorescence signals from the distance, and detects the elastically backscattered and fluorescence signals.
