Abstract:
1. A system for detecting airborne agents, comprising: a laser source configured to provide laser pulses of at least two wavelengths; a transmitter configured to transmit the laser pulses; a coupling mechanism configured to remotely couple the laser pulses between the laser source and the transmitter, said coupling mechanism comprising 1) a fiber optic connected between the laser source and the transmitter and 2) at least one focusing lens configured to divergently couple said laser pulses into the fiber optic; a receiver configured to receive elastically backscattered signals and fluorescence signals from the airborne agents; a common telescope configured to focus a laser beam transmission of the laser pulses from the transmitter to a far field and to receive the elastically backscattered signals and the fluorescence signals from the far field; and a detection system comprising at least one of a backscatter optical detector configured to detect said elastically backscattered signals and a fluorescence optical detector configured to detect the fluorescence signals from the airborne agents.
