What is the typical wavelength range for lidar systems?

The typical wavelength range for lidar systems generally falls between 700 nm to 1550 nm, making this answer the most accurate. This range is particularly favored because it allows for optimal performance in terms of atmospheric transmission, sensor sensitivity, and the ability to penetrate various materials.

The 700 nm to 1550 nm wavelength range encompasses the near-infrared region, which is ideal for many applications such as forestry, agriculture, and environmental monitoring. These wavelengths enable lidar systems to provide high-resolution data while also minimizing interference from atmospheric gases, which can affect measurements.

Other choices present ranges that either extend into ultraviolet or far-infrared wavelengths, which are less practical for typical lidar applications. For instance, the 300 nm to 800 nm range overlaps the ultraviolet and visible spectrum, and while some specialized applications might use this range, it is not the standard for most lidar systems. The 1000 nm to 2000 nm range moves into the infrared spectrum that is less commonly utilized for conventional lidar systems, and the 400 nm to 700 nm range does not capture the full spectrum that lidar systems typically use.

Thus, the choice of 700 nm to 1550 nm is grounded in the optimal operational parameters for lidar technologies,
