Pain - The Weapon of Choice for the US Police? Portable pain weapon in police hands - New Scientist

Portable pain weapon may end up in police hands - tech - 30 September 2009 - New Scientist

HE Pentagon's efforts to develop a beam weapon that can deter an adversary by causing a burning sensation on their skin has taken a step forward with the development of a small, potentially hand-held, version. The weapon, which is claimed to cause no permanent harm, could also end up being used by police to control civilians.

The idea of the weapon is to "create a heating sensation that repels individual adversaries", according to the Joint Non-Lethal Weapons Directorate (JNLWD) in Quantico, Virginia, which develops less-lethal weapons for the US military and coastguard.

Tests with a rifle-mounted infrared laser, carried out at a US air force lab near Dayton, Ohio, have determined a combination of laser pulse power and wavelength that causes an alarming, hot sensation on the skin, but which stops short of causing a burn, says JNLWD project engineer Wesley Burgei.

"We have established the minimum irradiance to cause a sensation and have characterised where thermal injury begins," he says. "But the exact operating irradiance which balances a useful military effect with a conservative margin of safety has not been nailed down yet."

That's something that will have to be done before the weapon is deployed, as too powerful a laser beam could permanently blind someone if fired at their eyes. Weapons that do this are banned under the UN Protocol on Blinding Laser Weapons.
