We have been developing a measurement system for microstructures using a small-diameter optical fiber probe. The contact detection method using a threshold value may cause a large error due to the time lag between the real contact time and the time d

This paper presents a system for measuring micro holes that makes use of an optical fiber probe. The optical fiber probe is deflected when it comes into contact with a hole surface, and this deflection is measured optically. For this research, the op
