Optical Filter For Lidar Laser Sensors

Published on

Airborne laser scanning, also commonly known by the acronym LiDAR (Light Detection And Ranging) is an active remote sensing technique, used to record the surface of the earth, specifically the topography of large areas of terrain and objects appearing on it. is a rapid, highly accurate, and efficient method of capturing 3D data of large areas, such as agricultural or forestry sites, urban areas, and industrial plants. LiDAR (laser detection and ranging) can provide a point cloud of data that precisely describes the position and velocity of objects in the field of view of the system through analytical methods such as time-of-flight or coherence.

LiDAR laser sensor systems work with common laser wavelengths including 532nm, 905nm, and 1064nm. Each wavelength presents engineers with tradeoffs for consideration, including the effects of water on signal integrity, power consumption, and the availability of sensor components. Regardless of the wavelength employed, Optolong provides customized optical filters for LiDAR sensor applications providing “More Signal, with Less Background”, from the design and manufacture of initial prototypes through to high volume production in our ISO9001:2015 certified China operation.

Optolong optical filters for LiDAR sensors offer high performance characteristics:

High transmission at the laser wavelength (>95%)

Narrow bandwidths (<1nm to 40+ nm dependent on the system requirements)

Deep blocking (OD 4-6 over detector range)

Highly stable, environmentally robust and reliable

Wider angle of incidence range (AOI) 0-35 degree

Low cost, high volume manufacturing capabilities
