Arecibo ray tracing diagram
Arecibo ray tracing diagram A cartoon ray tracing diagram of rays reflected off of the primary 305-meter dish (not shown), bouncing off of the secondary reflector (upper right), reflecting off of the tertiary mirror (center left, not labeled), and focusing in to the feed at the corner of the receiver room. For a more detailed ray trace, see Kildal, Johansson, Hagfors, and Giovanelli 1993: Analysis of a cluster feed for the Arecibo trireflector system using forward ray tracing and aperture integration.
