Laser dazzler emitting three-colour radiation




The article presents a laser dazzle generating three overlapping laser beams of different colours and an analysis of the possibility of dazzling people with this radiation. The analysis took into account the eye’s photopic sensitivity and the additivity of the three radiation beams. Such analysis, to the knowledge of the authors, is presented for the first time. The possibility of dazzling for four different dazzle levels and three levels of ambient luminance was presented. It has been shown that in some conditions it is possible to damage the eye without causing the assumed dazzle effect.
