Abstract：To investigate the application of line laser in the construction of the optical testing path which based on its ability to no-contract output continuous reference datum, the assistant role of the line laser in testing different types of mirrors has been studied, such as plane mirror testing, spherical mirror testing, Ritchey-Common testing, aspheric mirror testing etc, and the operational guidance in the adjustment has been proposed, that scientifically and systematically demonstrate its special advantages in spatial position and optical axis correction, also the interference of its error to the testing and the corresponding correction measures has been discussed, then verified the advantages by experimental comparison with the traditional equipment. The results show that the line laser can replace the traditional auxiliary alignment equipment and methods, and it has good adaptability for different types of optical mirror testing.
