Abstract

A new measuring method of the SELFOO lens optical index on sxis n0 and quadratic gradient constant g by the equal object-image size imaging method (EOSIM) is proposed in this paper. The resulte obtained has shown that this method is significant in practical application, and it can also simplify the surveying instruments.
