Fig. 1: Bistatic MHz space debris laser ranging at Graz SLR station.
From: Space debris and satellite laser ranging combined using a megahertz system
The main SLR station (background) consists of a 0.5 m receive telescope with a 0.07 m laser transmit telescope attached to the main tube. The 0.8 m Ritchey Chretien telescope (foreground) is mounted in a narrow dome of approximately 2 m height and acts as the receiving station in the bistatic measurement setup. Due to the separation of ~10 m between transmit and receive optics, the receive telescope is outside of the field of view of the atmospheric backscatter of the laser beam.
