LiDAR Filter

Lidar stands for Light Detection and Ranging. It's a remote sensing method that uses light in the form of a pulsed laser to measure ranges (distances) to the objects. 

  1. Emitting a laser pulse: A laser emits a short, powerful pulse of light.
  2. Measuring reflection: The laser pulse travels through the air and reflects off objects it encounters.
  3. Calculating distance: The time it takes for the reflected light to return to the sensor is measured. This time can be used to calculate the distance to the object.

Comparison of LiDAR Wavelength
Wavelength Pros Cons
1550nm Excellent atmospheric transmission, high penetration, eye-safe Limited detector options, higher noise
905nm Good atmospheric transmission, wide range of detectors, lower noise Lower penetration, limited eye safety
1064nm High power, eye-safe Lower atmospheric transmission, limited penetration
532nm High sensitivity, good atmospheric transmission Higher cost, lower penetration

  • Selection Guide

    Different wavelength of laser may used in LiDAR system. Including:
    915nm, 905nm, 870nm, 1064nm, 532nm, 1550nm

    The bandpass filter should filter out the background light which will help the sensor get a better result.

  • Addressing Background Noise in Lidar Applications

    Factors Affecting Disturbance Light Noise:
    Distance: Longer distances can increase the impact of disturbance light noise because the target signal weakens over distance, while the ambient light remains relatively constant.
    Outdoor Environments: Outdoor environments are more susceptible to disturbance light noise due to factors like sunlight, atmospheric conditions, and reflections from surrounding objects.

    Background noise can significantly degrade the performance of lidar systems. While bandpass filters can be effective in certain scenarios,
