Abstract : The patent is related to countermeasures and particularly to an effective countermeasure against laser beam target designators. A laser beam target designator is a device for sending a laser beam to a target for attracting laser homing weapons. Laser energy is reflected from a target and the reflected laser energy when detected by a laser guided weapon is used for homing in on the target. The system of this invention is for interposing a non-toxic aerosol material between a laser source and a target to attenuate the laser beam without providing a visible trace of the absorbing medium. Experimental results verified the existence of several nontoxic liquid materials suitable for use in the system, such as Isopropyl alcohol, Butyl Cellosolve and Ethylene glycol.
