| Abstract: | The principle of cube corner array's approximate phase conjugation was analyzed. The cube corner array's restraining effect from wave front aberration of low spatial frequency was validated, and the optimization of array's cell number was researched, and the localization and effectual application field was pointed out. The result of simulation indicates that the focus energy concentricity of aberration beam was improved effectively by using cube corner array, and this new method could be used in restraining wave front aberration of low spatial frequency. |
