Frequnce Domain OCT (FDOCT) avoids axial scan to get imaging, so it can get higher imaging speed than TDOCT. In conclusion, FDOCT makes realtimeimaging come true.
Laser welding seams in titanium alloys with complex structure were detected by using realtimeimaging system in this paper, and the images of ray detection which contain tiny flaws were obtained.
