Choosing the appropriate Lidar wavelength is essential for optimizing performance in various applications. Different wavelengths offer unique advantages and limitations, influencing factors such as range, resolution, and environmental performance. This guide provides an overview of key considerations when selecting a Lidar wavelength for specific needs.
Common Lidar Wavelengths
Most Lidar systems operate within specific wavelength ranges, each suited to particular applications. The most common wavelengths include 905 nm, 1064 nm, and 1550 nm. These wavelengths differ in terms of eye safety, atmospheric attenuation, and reflectivity.
Factors Influencing Wavelength Choice
Several factors should be considered when selecting a wavelength:
- Application Environment: Outdoor or indoor use affects atmospheric interference and safety considerations.
- Range Requirements: Longer wavelengths generally provide better range and less atmospheric scattering.
- Object Reflectivity: Different materials reflect specific wavelengths more effectively.
- Safety Regulations: Eye safety standards vary with wavelength, influencing system design.
Application-Specific Recommendations
For short-range indoor mapping, 905 nm systems are common due to their affordability and sufficient performance. For long-range outdoor applications, 1550 nm wavelengths are preferred because of their higher power and safety advantages. Industrial and autonomous vehicle applications often select wavelengths based on environmental conditions and safety standards.
