High accuracy angle measurement method for remote sensing scanning system

To solve the conflict for the field of vision, image quality and detector level, the expansion of the field of vision for remote sensing is regard as an exigent requirement. Limited by the detector level, scanning remote sensing will be a useful means to extend the field of vision. Therefore, the precision for the scanning system is improved gradually. The high accuracy measurement method for scanning system is a crucial factor. Based on high requirement of angle measurement for scanning system, the underlying techniques for static and dynamic measure are clarified, and the detailed schemes with concretely applying condition are researched.
