Paper Abstract

The Smart, White-Light Dazzler (SWLD) is a nonlethal weapon designed to aim and deliver a dazzling and disabling light flash of maximum eye-safe energy to a selected target. The two key features of the SWLD technology are its self-aiming and power-adjusting capabilities; optical barriers, such as dark glasses, rifle scopes, binoculars, etc., and iris aperture, whether the eyes are light or dark adapted, are automatically taken into account by using a low-power infrared (IR) laser to probe and return a glint from the eye(s) of the target. Using the retro-reflected glint the dazzle pulse is adjusted and directed to arrive at the target with maximum allowable nonlethal energy at any range from 1 m to 100 m. The collateral risk of this technology is very small. If the weapon is misaimed dramatically, the returned glint may come from an unintended person who will then be dazzled. Although this person will be incapacitated for 2-3 minutes, he will suffer no long-term effects. We assume all persons in dangerous situations would rather be accidentally, temporarily dazzled than suffer more serious consequences. The SWLD adds an important tool to the spectrum of nonlethal responses available for use by military and law enforcement personnel. Applications include dispersing persons in crowd control and disabling terrorists in hijacking situations. The dazzle process may be repeated, choosing the next most susceptible target until a crowd is subdued. One important application in counter-terrorism is onboard planes where a pilot can fire a SWLD through a cockpit-door window and dazzle a hijacker with no damage to passengers.
