U.S. companies push laser sensors to improve the safety of driverless cars

The OFweek sensor networks according to the U.S. "Automotive News" reported on April 13th, located in the Silicon Valley Luminar unmanned start-up company said that the company is in the process of manufacturing laser sensor for unmanned vehicles, so as to improve the safety of unmanned vehicle.

Luminar driverless car company was founded in 2012, the founder of 2 optical experts. The chief executive Austin Russo (Austin Russell) said in an interview: "the company in Florida, Orlando is stepping up the manufacturing factory, the production of the first batch of 10 thousand sets of laser radar sensor later this year."

The laser pulses emitted by lidar sensors can be reflected by objects so that the autonomous vehicle senses the surrounding environment. Many experts in the field of unmanned vehicles believe that lidar sensors, like cameras and radar, are very important components.

Russell said: "the current market for unmanned automobile laser radar sensor, from the automatic driving car hardware development.". They are limited in observation range and resolution, and can not guarantee the safety of unmanned vehicles."

Luminar solved these deficiencies by using 1550 nm wavelength. Compared with the rival's best radar sensors, the resolution has been increased by 50 times, and the range of observation has been increased by 10 times. This means that the car can clearly see "black objects" that are 200 meters away.

By contrast, Velodyne's "Puck" lidar sensor can only observe objects within 100 meters. Russell said: "manufacturers should concentrate on improving the performance of radar sensors rather than lowering prices, so that the price of driverless cars will be closer to the people.". As the price goes down, the performance of the car will drop."
