Many firearms help the user ensure they are aiming accurately by shining a laser beam onto their target.
If this happens to be a suspected criminal, they may look down, see the spot and realise their predicament…but they may not.
Today’s invention is an attachment for such a laser equipped weapon which modulates the outgoing laser beam into digital bursts. It can detect any reflected light and determine the distance from the target.
This allows a lens system to deflect part of the beam upwards to where the face of the target person should be…alerting them to the fact that they are in danger.
