LiDAR

Light Detection and Ranging (LiDAR) is a technology that can detect distances, directions, and speeds to objects by investigating the laser on a targets, and is used for more precise observation and measurement using laser's advantages.
In these days, most cars have a various Advanced Driver Assistance Systems(ADAS), such as automatic cruise control, lane keeping and parking assist.
In this rapidly commercializing & evolving environment of autonomous vehicles, Optrontec is providing various LiDAR essential optical components.
