What is the best wavelength for automotive lidar?

Have you ever wondered why all automotive lidar systems use laser diodes emitting at either 905 nm or 1550 nm? In this report, you will learn why this is the case. Oh and even more interesting, you will finally get to learn which wavelength is best for automotive lidar. The question we focus on in this report is an important one since advanced automotive lidar is a key component in future self-driving cars. As you probably already know, lidar stands for light detection and ranging. It is a...
