This picture taken by Rod in 1953 is the 32
dish solar grating interferometer which was used by Christiansen to compute,
for the first time, a 2D earth rotation aperture synthesis image. For more
details, read the Recollections of two and a half years with `Chris'
published in the Journal of Astronomical History and Heritage, and
Radio Astronomy at
Potts Hill. Rod Davies spend the period Feb 1951 to Aug 1953 in
Christiansen's group at CSIRO Radiophysics in Sydney and at the Potts Hill
field station, where Rod made his first pioneering 21cm H-line observations
and entered a field of research that dominated much of his later career at
Jodrell Bank.". Sadly, Rod Davies passed away in Nov 2015 (obituary for Rod
by Simon Garrington). - Text thanks to Ron Ekers (CASS).
