LIDAR stands for ‘Light Detection And Ranging’ sensors. These highly versatile devices can send and scan a pulsed laser through an environment and calculate the exact sensor orientation and position to determine the reflected signals’ return time.
The most significant component of LIDAR sensors are their filters which separate target signals from others and prevent external light, including sunlight, from hitting the detector. By using this method, you can measure the precise distance of any object on the surface of the earth. The LIDAR system can use a range of filters depending on its use.
The right choice of filter is critical because these sensors are usually mounted to UVAs, satellites, autonomous vehicles, and various other platforms that need to operate in harsh environments for a long period with minimal maintenance. Most LIDAR filters are thin-film ultra-narrowband interference filters that don’t block the target signals from reaching the filter.
There is a wide range of LIDAR filter uses and applications in various industries.
The advanced LIDAR filters used in LIDAR systems help in space research and development. These filters can work in high-temperature ranges and harsh environments without needing maintenance for a long time.
Transportation agencies are utilizing high-quality filters in LIDAR systems to survey the infrastructure of roadways as an alternative to traditional tools and devices. These filters help with accurate data collection, which is a challenge with other tools.
In the automotive industry, the use of LIDAR filters is growing rapidly due to the development of autonomous vehicles. The automakers and technology companies utilize a LIDAR filtration system that enables cars to sense and respond to the surrounding environment precisely.
