Visual servoing-based approach for efficient autofocusing in scanning electron microscope
2013
2013 IEEE/RSJ International Conference on Intelligent Robots and Systems
Preserved Fulltext
Fast and reliable autofocusing methods are essential for performing automatic nano-objects positioning tasks using a scanning electron microscope (SEM). ...
In this paper, a new, fast and direct method of autofocusing has been presented based on the idea of traditional visual servoing to control the focus step using an adaptive gain. ...
