| Abstract: | A new method of measuring the focal length based on the wedge-plate shesring interferometric tech-
nique is presented. This method adopts the change of the fringe orientation to determine the focal length, and hence
it has the advantages of simple apparatus, convenient adjustment and high accuracy.In addation, it can also be used
in invisible regions. |
