AbstractA primary mirror is the key component for telescope. For getting high-quality primary mirror the most important work is to measure and control glass stress distribution. At present small size glass can be accurately measured, but how to measure large mirrors has not been broken though. For developing measurement technology, a new method by making use of reflected mirror to extract polarized beam is brought forward to measure large glass. At first, theory analysis has been done that is about the interaction between polarized beam and reflected mirrors. Then experimental measurement has been carried out by use of the method. A conclusion which can be drawn out is that by controlling the refractive index and thickness of reflected coating, polarization state of reflected beam can be kept in the same state to the incident beam when the polarized beam passes through the reflected mirrors.; A primary mirror is the key component for telescope.
