For Sale What is LiDAR for drones? Seeing With Lasers

LiDAR is an acronym for “light detection and ranging,” (sometimes Light Imaging, Detection, And Ranging). Like sonar and radar, LiDAR relies on the same principle: echolocation.

Although it sounds like Star Wars space science, echolocation has been around for millions of years and happens to be a critical tool for a little flying mammal – the humble bat. Bats use sound waves — issuing a squeak that bounces off an object that returns to their ears sooner or later depending on how far away the object is. Tracking how long it takes to come back tells the bat the distance and location of prey—or death by tree.

Fast forward to naval sonar, which sends a bigger click into the surrounding water and listens for echoes. Knowing how fast sound travels in water, operators can tell exactly how long it took to hit something and come back, telling them precisely how far away it is.

Radar, the next big advance, does much the same thing with radio waves. The familiar radar dishes we’ve all seen fire out a beam of radio waves. When those waves hit something solid they bounce back and the dish detects them. Since we know the exact speed of light we can calculate the distance of the object hit. But radio waves have limitations. They don’t detect some objects, and don’t work well below an elevation of 100 feet.

Now we have 3 types of LiDAR with mass deployment.

TF01/TF02,Single-point Ranging LiDAR. It is applicable to various flight control brands including Pixhawk4, APM, TopXGun, EFY Tech, JiYi, aiAero and DAISCH etc.

TFmini, Micro Single-point Ranging Module. It has advantage for close measurement and can be widely used in the integrated application of drones, robots and industrial equipments.

CE30, a solid-state LiDAR with large FoV. It could simultaneously output grey and depth information within 132° horizontal FoV and 9° vertical FoV. Meanwhile no mechanical rotating components exist internally, so higher reliability and stability could be ensured.
