激光在人类进化中发挥了重要作用, 激光似乎一直在使新事物成为可能. 然而, 您知道吗，激光也让生活在数百年前的人们受益，让我们更多地了解它们的存在?
现在几代人, those living near Johannesburg in South Africa have long suspected that a “lost city” existed in a place called Suikerbosrand. 然而, thick vegetation has made it almost impossible for this city to be examined closely. But recently, an intricate laser system shed new light on the city and revealed that it did, in fact, exist.
Karim Sadr, a professor at the School of Geography, Archaeology, and Environmental Studies at the University of the Witwatersrand, used LiDAR (Light Detection and Ranging) technology earlier this year to unearth new findings about the city. He was able to take a closer look at almost 8 square miles of land, and he found more than just individual homesteads that suggested a village may have existed. He found evidence that an entire city was once set up in the area complete with more than 800 homesteads and somewhere in the neighborhood of 10,000 people. The city was believed to be inhabited by those who spoke the Tswana language from sometime in the 15th century until about 200 几年前.
The fact that LiDAR found so many remnants of this “lost city” is exciting because it now gives researchers more of a reason to investigate the city further. It will be well worth their time to start digging around in the area more to see what else they can discover.
LiDAR is also further proof that lasers are playing a more important role in our world than ever before. Seiffert Industrial understands this and utilizes lasers in a variety of ways in the industrial world. 联系我们 800-856-0129 today to see how laser technology might benefit you.
