So adjusting the drift of laser beam and improving its directional stability, which is the key technology in the domain of the linear reference technology, demands to be solved
可見，抑制激光光束漂移，改善其方向穩定性是直線基準技術領域急需解決的關鍵技術。 -
The laser beam treated as a linear reference is used widely in the manufacture and measurement equipments, due to its many advantages, such as high brightness, good directivity, and good coherence etc. but the further improvement of the laser directional stability accuracy is restricted by some factors, such as the environment etc, which restrain the application greatly in the ultra - precision manufacture and measurement equipments
激光光束由於其亮度高、方向性好、相干性好等優點，常被作為直線基準廣泛應用於加工和測量設備中。但由於受環境狀態等因素的影響，制約了激光方向穩定精度的進一步提高，限制了激光在超精密加工和測量設備中的進一步應用。
