Abstract

A test is described, which serves as a self-check of the optical part of a lidar system. Several lidar signals using different parts of the lidar telescope are compared. Differences in these signals indicate range dependent transmission changes of the optical receiver, resulting in signal distortion. A systematic approach including comparison with ray tracing simulations of the optical system can point out causes of the deviations.
