... Astrophysics Group . ... COAST Technical Details . ... The beam from each telescope passes through an aluminium tube, which serves to isolate it from the atmosphere, into the beam combining building. ... Inside the beam combining building the outer annulus of each light beam is separated and used in the acquisition and autoguider system. ... A simple algorithm is then used to detect the offset from the centre of the field, and this is corrected using piezo-driven mirrors at the back of the...
... The design employs a differential structure. ... The input is adapted to 100 differential, and the outputs use standard Low Voltage Differential Signaling (LVDS). ...
