Our core competency in R&D:
The innovation of magnetically resonant scanning technology.
Doiphin's pioneering magnetically resonant scanning actuator operates at an impressive high-speed up to 18,000 rpm, and push the boundaries of physical scanning angles.
Owning to Dolphin's scanning technology, we've managed to drastically reduce the electronic components required for our LiDAR system to just 1/200 to 1/360 of that of our industry competitors. This fundamental breakthrough has led to a significant cost reduction in 3D-LiDAR technology, bringing it down from tens of thousands of dollars to merely hundreds.
