The surface figure changes of menisctls primary mirror
centrally supported and loadedby the gravity(1g)
are studied. The PV and RMS values are used to determine whether thedeformation is reasonable or not. Data processing is done with the help of zernikepolynomials
the aberration composition of the mirror Supported in this way is found'
andsome approaches to improve image quality are carried out. At last the rear profile of themirror is optimized.
