Under the Hood of Luminar’s Long-Reach Lidar – IEEE Spectrum
http://spectrum.ieee.org/cars-that-think/transportation/self-driving/under-the-hood-of-luminars-long-reach-lidar Current automotive lidars scan their surroundings by firing pulses from semiconductor diode lasers emitting at 905 nanometers in the near infrared and recording reflected light to build up a point cloud mapping the car’s surroundings. But laser-safety rules in the U.S. and other countries restrict the power in the laser pulse, limiting the lidar’s →
