Cost Higher than 905 nm Lower due to technical maturity Range Potentially longer range due to higher sensitivity Shorter range (up to approx. 200 meters) Eye Safety Concerns with power limitations Significant eye safety concerns; more power is needed to achieve the same range as 905 nm LiDAR, which can also be harmful Performance Higher sensitivity for longer range and better resolution Performs better in rain and snow Ambient Light Better performance in low ambient light conditions (e.g., dawn, dusk, cloudy days) More susceptible to solar interference during daylight Atmospheric Higher sensitivity to humidity Less affected by humidity, making it suitable for autonomous driving in humid environments
