Zusammenfassung: | A simple safety framework for laser eye dazzle, based on a complex model developed from
human subject experiments, is proposed to address the urgent need for guidance within
international laser safety standards. Maximum Dazzle Exposure (MDE) safety limits are
derived that set the laser irradiance at the eye above which an object cannot be visually
detected. A newly defined concept of dazzle level accounts for the extent of visual
obscuration, and different ambient light levels are accommodated by determining safety
limits for night, dusk/dawn, and day conditions. The resulting table of MDE values allows
dazzle effects to be quantified in simple safety calculations across a wide range of
scenarios. This safety framework is intended to empower the laser safety community to
understand and quantify the impacts of laser eye dazzle, specify protection measures for
those at risk, and assure the safety and effectiveness of laser dazzle devices. |
