随着技术的快速发展,激光雷达成为自动驾驶和无人驾驶中的关键器件。为了高精度地检测汽车在运动和静止时周围环境的距离,激光光束必须被整形为一个具有固定视场角的光场。

本次炬光科技获奖产品广角光束匀化扩散器使用了世界领先的光束整形技术,即使在极端的工作环境下(-40℃~150℃),也能使激光光束的强度分布保持高度一致、稳定,为智能驾驶、三维感知和探测提供了可靠的保障。

炬光科技广角光束匀化扩散器的创新关键点

•  宽至160°的视场角

•  透射率高(>90%),能量损耗低

•  光束强度空间分布均匀(均匀度>90%)

•  光斑边缘陡峭

•  高损伤阈值 (>6J/cm²@3ns),即使在高强度下使用,也能提供稳定的光学性能

•  无亮爆点(无零级衍射),对人眼安全

•  高温条件下有效可靠(150℃)

•  批量应用的微光学玻璃晶圆技术, 满足低成本高质量的制造需求
