Paper Abstract

Proposed a high-precision focusing method according to practical application-- Dual Beam Focusing method. And in accordance with geometrical optics theory introduced the basic principle of the focusing method, analyzed the error of this method, given an conclusion of the maximum error and the error during focusing when this method applied to telescope and microscope separately. Supported examples of applied this method to telescope system, microscope system and camera system. This method is simple and practical with high precision.
