A beam director may take the form of a siderostat, or a
Coude' telescope of Alt-Az, Alt-Alt, or equatorial configuration.
DFM Engineering has built a Alt-Alt (altitude over altitude)
beam director/Tracker (BD/T) with a 0.8 meter aperture and
a Coude' optical system.
This system is located at the US Air Force Maui Optical Station
and has been used for many experiments.
We have also built two smaller beam directors of the altitude
over azimuth (Alt-Az) Coude' configuration.
Coeleostats: A coeleostat is typically a siderostat,
but the word is poorly defined. The name may also be used
to describe a beam director.
