Measurement of divergent angle width of laser beam with CCD for determination of radius of curvature of cylindrical lens

This paper presented a method for measurement of radius of curvature of a cylindrical lens. While a laser beam goes through a cylindrical lens, the divergent angle width can be precisely determined with a high resolution CCD and a data microcomputer processing system. Then the radius of curvature of the cylindrical lens also can be calculated out. In practical application, measuring accuracy is high up to 2%.
