Lidars

Simply put, Hesai lidars are superior devices that allow a vehicle to sense its surroundings, enhancing safety and reliability, but they do not store information.

None of the company's sold vehicles have lidars.

What emerged is largely custom, from the sizable under-the-trunk PC to the roof-mounted sensor stack consisting of multiple lidars, cameras, radars, and GPS.

Given these costs, car manufacturers are still testing different technologies and other than Velodyne no manufacturer has so far sold Lidars in big numbers, she says.

For example, applications of high-energy laser weapons and lidars require precise knowledge of how much transmitted power actually illuminates the target.

The Doppler broadening of gases in motion allows the determination of properties via the resulting frequency shift. citation citation Scanning lidars, such as the conical-scanning NASA HARLIE LIDAR, have been used to measure atmospheric wind velocity.
