激光雷达，可永久损坏摄像头

Core Viewpoint - The increasing prevalence of lidar and high-power lasers in automotive and entertainment sectors poses a risk of permanent damage to smartphone cameras, necessitating user awareness and precautionary measures to avoid direct exposure to laser beams [1][2]. Group 1: Risks from Lidar - Lidar devices used in vehicles, such as the Volvo EX90, can emit near-infrared laser beams that may permanently damage smartphone camera sensors if directly exposed [1][2]. - Volvo has confirmed that this issue is not isolated and advises users to avoid pointing cameras directly at lidar sensors to prevent potential damage [2]. Group 2: General Laser Risks - Laser beams, including those used in entertainment, can also harm camera sensors, as reported by users experiencing issues with devices like the Samsung Galaxy S24 Ultra after exposure to laser events [2]. - Experts warn that while laser light is generally safe for the eyes, direct exposure to camera sensors can lead to damage, as camera sensors are more susceptible than human eyes [3]. Group 3: Precautionary Measures - It is recommended to maintain a safe distance when photographing lidar-equipped vehicles and to use filters or lens caps for additional protection [2]. - During laser shows, audience members should take precautions to avoid direct laser exposure to their camera lenses, such as shooting from angles that do not align with the laser source [3].
