摘要：

Aspheric optical surfaces are often tested using computer generated holograms (CGHs). CGHs can generate any desired wavefronts to realize phase compensation. In addition to fabrication errors of CGH, adjustment errors of testing system can seriously affect the precision of aspheric surfaces testing. In order to eliminate adjustment errors of CGH and the tested aspheric, this paper designs a new layout of CGH that has the advantages of high adjustment accuracy and simple experimental operation. What is more, this paper provides a full set of design idea and design process for the engineering application of aspheric surfaces testing. Finally, combined with the current international processing and testing levels, simulation analysis results of all kinds of errors in the aspheric testing system, which shows that this system meets the requirements of high precision aspheric surfaces testing.
