| Abstract: | A new experimental scheme of measuring lens focal length has been put forward on the basis of the improved laser plate shearing interfe rence method. The parallelism of two sets of interference fringes is taken as a criterion according to the node property of lens in this scheme. It has the advantages of simple measuring process and high accuracy. |
