For the SLR system to be described, it has been decided to use the bistatic approach. The two separate telescopes are spaced by about 2 meters and are using identical azimuthal mounts. A 130 mm diam. lens is used for transmitting the laser beam and a 450 mm parabolic mirror for the receiver. Each telescope is enclosed by an independently driven housing isolating it from wind forces as well as environmental contamination thus enabling even a use without any dome. The telescopes are driven by direct on-axis motors which are controlled by built-in digital servo systems. Moving cables are avoided by sliding contacts allowing a continuous rotation in both axes without limitation. The focal units of each telescope are mounted in separate boxes below the platform of the observation building. The transmitter box contains the variable beam expander and the receiver box contains the filters (spatial and spectral) as well as the photoelectric receivers.
