LiDAR Service

LFT’s LiDAR reflectance meter measures the Bidirectional Reflectance Distribution Function (BRDF) in specific angular relationships. BRDF measurements are usually performed by specialized test houses or institutes.

For most materials, few backscatter values are available in the literature. If at all, usually only the angle dependent scattering at perpendicular illumination, are given. For oblique incidence, usually no measured values can be found.

With our LiDAR reflectance meter we offer a unique service, which makes it possible to measure the optical backscatter of different scattering objects (traffic signs, vehicle paint, etc.).
