Abstract
The small diameter and relative flexibility of optical fiberscopes provide potential flow measurement solutions for difficult to access closed vessels and enclosures. The use of a pair of optical fiberscopes in conjunction with a stereo particle image velocimetry (PIV/PTV) system, in an un-optimized configuration, may lead to lead to gradual erosion of the transmitted image. In the present study, we analyzed the interpolation error at subpixel distances because of the spatial resolution imposed by the diameter of each fiber. Our analysis confirmed that PTV-SS method (Tani et al 2001) can be applied to a fiberscopic stereo PIV system.
