8th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Large Mirrors and Telescopes.
The PSS (pentaprism scanning system) has advantages of simple structure, needless of reference flat, be able of on-site testing, etc, it plays an important role in large flat reflective mirror’s manufacturing, especially the high accuracy testing o
