The extreme environment of Antarctic greatly benefits astronomical observations. Site testing works already show the
excellent seeing and transmission on Dome C. And the higher, colder inland plateau Dome A is widely predicted as even
better astronomical site than Dome C. Preliminary site testing carried out since the beginning of 2008 shows that Dome
A has lower boundary layer and lower precipitable water vapour. Now the automated seeing monitor is urgently needed
to quantify the site's optical character which is necessary for the telescope design and deployment. We modify the
commercial telescopes with diameter of 35cm to function as site testing DIMM and make it monitor both seeing and
isoplanatic angle at the same time automatically on Dome A at different height. Part of the processed data will be
transferred back by Iridium satellite network every day. The first DIMM will be deployed on Dome A in early 2011.
An iterative deconvolution algorithm is presented in detail which utilizes regularization to combine
maximum-likelihood (ML) estimate of convolution error and several physical constraints to build error
function. The physical constraints used in this algorithm include positivity, band-limit information and the
information of multiple frames. By minimizing the combined error metric of individual ones, the object can
be expected to be recovered from the noisy data. In addition, numerical simulation of Phase Screen distorted
by atmospheric turbulence following the Kolmogorov spectrum is also made to generate the PSFs which are
used to simulate the degraded images.
