Abstract :
The authors propose a new system for sensing the position of a slim marker using phase detection to enhance position accuracy. A slim wireless LC resonated marker (1.2 mm in diameter and 10 mm long) was fabricated and a detector was formed by connecting high-speed AD converters. The system has a position accuracy of around 1 mm, and it can be used for highly accurate position sensing without magnetic shielding because it is free from earth field.
