The telecover test: A quality assurance tool for the optical part of a lidar system 2/2
b'A test is described, which serves as a self-check of the\\noptical part of a lidar system. Several lidar signals using\\ndifferent parts of the lidar telescope are compared.\\nDifferences in these signals indicate range dependent\\ntransmission changes of the optical receiver, resulting\\nin signal distortion. A systematic approach including\\ncomparison with ray tracing simulations of the optical\\nsystem can point out causes of the deviations.'
