Abstract

The optical design comprises the photometrical calculation, the modeling of the image formation and the optimization of the optical system. This is also true for lidar and leads to specific aspects in the optical design for lidar. The lidar-equation is corrected for near distances, and it is shown that there is a difference between the photometrical calcuation of lidar systems and conventional optical systems. Moreover, for the image formation with coherent radiation one has to apply the formulas which differ from the conventional formulas for incoherent image formation. The generalized formulas for laser image formation are given. Finally, there are shown optimized lidar optical systems: classical on-axis and off-axis mirror systems and also alternative lens- and lens-mirror-solutions.
