How do self-driving cars “see”? – Sajan Saini

Take a look at the LIDAR and integrated photonics technologies that help self-driving cars navigate obstacles, no matter the environment, weather or light.

It’s late, pitch dark and a self-driving car winds down a narrow country road. Suddenly, three hazards appear at the same time. With no human at the wheel, the car uses smart eyes, sensors that’ll resolve these details all in a split-second. How is this possible? Sajan Saini explains how LIDAR and integrated photonics technology make self-driving cars a reality.

  1. So when these things grow in popularity, how safe are they going to be for incoming traffic? When I'm driving down a single lane highway and someonens coming at me with their headlights on its uncomfortable for a few moments. But if I'm constantly exposed to lasers as I meet these vehicles on the single lane highway what will that do over time to my eyesight?

  2. light "waves" do not interfere with each other. They are not like ripples in a pond either. and how would the light be slowed down? light travels at a constant velocity, C. it may seem to go slower in denser mediums but that's because there are more particles in the way, making the light bounce around more and travel in less of a straight line, making it appear to go slower. Is this a kids show? because, like grade school, everything has been oversimplified to the point of being WRONG!!

  3. I studied physics then dropped out of my full ride with my kid years ago. I did develop an ego because of it because I thought I knew everything. Finding years’ old videos of Ted that I hadn’t realized I missed completely, I realize I know nothing.

  4. 어릴 때는 공상과학 영화에서만 나오는 내용이라고 생각했지만, 지금 실제로 시험 운행 중에 있는 자율주행 자동차들을 보면 정말 기술이 많이 발전했다는 것을 느끼고 있습니다. 저는 자율주행 자동차들이 내장되어 있는 카메라로 주변 환경을 본다고 생각했는데, 이 영상을 보니 오히려 박쥐가 초음파를 이용해 길을 찾는 방법과 더 유사한 것 같습니다. 유익한 영상 감사합니다!

  5. “Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.” – Einstein.
