自動駕駛汽車如何「看得見」呢？

時間很晚了，天很黑，有一台自動駕駛汽車在鄉村道路上迂迴行駛。突然，三樣危險物同時出現。沒有人在操作方向盤，這台車需要有聰明的眼睛，即能夠瞬間判斷分析這些細節的感測器。這有可能嗎？沙珍 · 賽尼解釋雷射雷達和積體光學技術如何讓自動駕駛汽車成為可能。

Self-driving cars navigate pitch-black roads and sudden hazards using advanced sensors inspired by both radar and the internet’s pulse of data. LIDAR’s invisible infrared lasers can spot details as tiny as a button on a distant shirt, while integrated photonics shrink complex technology into chips smaller than a tenth of a millimeter. By combining rapid-fire laser pulses and ultra-precise detectors, these systems achieve depth perception more than a hundred times sharper than human vision. This powerful partnership allows cars to react instantly, seeing through darkness, weather, and uncertainty.
