Why microLiDAR™ by LightWare?


What makes LiDAR so special?

LiDAR sensors work on the Time of Flight (ToF) principle, where laser light pulses are emitted into the environment. These pulses reflect off surrounding objects and return to the LiDAR receiver. The time taken for each pulse to return to the receiver is used to calculate the distance it travelled. This ToF process is repeated numerous times with multiple nano-second pulses emitted and received to determine the most accurate reading. The formula to measure the exact distance of an object is: 

The distance of the object = (speed of light x time of flight) / 2

LiDAR is also eye-safe and highly accurate! Since it generates its own light source, LiDAR is effective during the day or night. It performs especially well in difficult conditions such as shadows, sunlight or glare.   

Key benefits of LightWare’s microLiDAR™

  • Small Form

Designed for size and weight constrained applications, LightWare microLiDAR™ sensors weigh as little as 8.8 grams and measure as small as 22 x 34 x 21 mm. This is the essential benefit that sets LightWare microLiDAR™ sensors apart from the rest!

  • Accuracy and precision

Fast update rates of up to 20 000 measurements per second make LightWare microLiDAR™ sensors extremely precise. This accuracy is not affected by the color or texture of the surface, nor the angle of incidence of the laser beam.    

  • Reliability

Mounted in a vertical or horizontal lens orientation, all LightWare microLiDAR™ sensors emit light at a wavelength of 905 nanometers (nm), providing an ideal balance between reliability and eye safety. Shorter wavelengths are more hazardous, whereas longer wavelengths are less reliable.   

  • Safety

In accordance with the international standard IEC 60825-1:2014 ‘’safety of laser products’’, all LightWare microLiDAR™ sensors are designed to Class 1M laser safety classifications.  

  • Plug and play connectivity 

All LightWare microLiDAR™ sensors are designed for seamless ‘plug and play’ integration with flight control tools and interfaces such as Pixhawk, ArduPilot, PX4, Arduino and Raspberry Pi.   

  • Privacy

As data privacy and protection demands increase, LightWare microLiDAR™ sensors play an important role in that they process objects and not images. This ensures no invasion of privacy.

Fit for multi-use: microLiDAR™ 

LightWare microLiDAR™ sensors provide enhanced 3D depth perception for UAVs and ground robots of any size. This gives your machine ‘’eyes’’ to safely navigate surroundings, detect movement, objects, and measure distances at rapid speed. Our microLiDAR™ sensors have a minimum scanning range of 50 meters in bright sunlight, making it ideal for a wide range of applications including altitude measurement, obstacle detection, sense and avoid, SLAM (simultaneous localization & mapping), and more: 

Specific microLiDAR™ applications

  • Detect and avoid

With the microLiDAR™ sensor mounted in a forward-facing position on the UAV, you are assured that stationary and moving objects are avoided. 

  • Height above ground

For use-cases like photogrammetry, observation, monitoring and surveillance, the microLiDAR™ sensor is mounted in a downward-facing orientation to keep track of the UAVs altitude above ground. 

  • Terrain following

Important for when a UAV flies over hilly, unpredictable or GPS compromised terrain, the microLiDAR™ sensor is mounted in a downward-facing orientation to keep track of changes in topography on the ground below. 

  • Obstacle detection

Most commonly, the microLiDAR™ sensor is mounted in a forward-facing position on the UAV to allow it to detect a still or moving obstruction on the path ahead.

  • Simultaneous localization and mapping (SLAM)

Operating beyond a visual line of sight (BVLOS) in a GPS denied area – such as underground or under a roof – SLAM allows the UAV to self-navigate while plotting a map of its environment. 

  • Collision avoidance

The microLiDAR™ sensor is mounted in a forward-facing position on the UAV, to ensure its safe operation by sensing other flying objects and navigating around them.   

  • Position hold (hover)

Important for when a UAV is required to fly at a specific and safe distance from a particular object, maintaining this position for monitoring, surveillance and inspection activities.
