Hesai and TГњV Jointly Released the "Eye Safety of Laser Products White Paper"
As is known, the human visual system has a strong reaction to laser light in the visible spectrum (such as red and green), thus spontaneously avoiding excessive laser radiation. However, the human eye is not responsive to invisible laser light (such as ultraviolet and near infrared light), unable to sense either its brightness or color. Therefore, prolonged exposure to intense invisible laser will cause irreversible damage to human eyes.With the growing application of laser technology to new areas such as facial recognition, autonomous driving, and laser projection, human eyes are ever more exposed to laser radiation. Without strictly regulating the eye safety level of laser products, users can face severe hazards.At the signing ceremony, MENG Ying, who is in charge of laser safety at Hesai, and XIN Hai, laser safety specialist at TA?V, jointly released the white paper and introduced its main contents, including: why laser can affect eye safety, the definition of laser safety levels and protective measures, the eye safety solution of laser products, and the development of laser product eye-safety regulations. The white paper also uses automotive LiDAR as an example to systematically explain an eye safety solution using near infrared lasers.
