To substitute for a traditional replication technique, an in-situ fatigue crack observing system for\udrotating bending testing machine has been newly developed. For verifying performance of this observing\udsystem, fatigue tests were carried out by using fatigue specimen having a small artificial defect. It is proved that\udthis system can be detect a small fatigue crack and its propagation behavior
