Measurement of Energy Distribution and Analysis of Hazard Probability of Long-Distance Laser Irradiation,
Abstract
To appreciate laser safety, we introduce a beam spot method of measuring long-distance laser irradiation. Based on laboratory eye injury data, we calculated the laser beam divergence, energy distribution over the laser cross section, and laser beam hazard probability. With the ever-wider applications of laser technology and with advances in designing related equipment, such as laser ranging, laser communications, lidar, laser target indicators, etc., laser safety has become one of the critical issues faced by researchers. In particular, since the human eye focuses on the laser beam, low irradiation exposure may cause serious eye injuries.
