Abstract
For high resolution electro-optical payload, the alignment and assembly of the secondary mirror with respect to the primary mirror is the most important step of the whole camera assembly process. For the purpose of the secondary mirror alignment, Wave front sensor and Collimator would rather be useful than the interferometer because of its small size and easiness of handling. In this paper the brief alignment procedure and method of the secondary mirror of a high resolution electro-optical camera system was introduced.
