| Outline of Final Research Achievements |
Using the short multimode fiber(SMMF) with length 8.8mm and diameter 0.125mm made from graded index multimode fiber for optical communications as an imaging probe, basic characteristics such as imaging condition, spatial resolution and wavelength-dependence have been studied theoretically and experimentally, and the reflection images of chicken tendon were measured using 635nm LED as a light source. Further, the SMMF (L:5mm and D:0.125mm) was combined with the full field OCT, and the axial and lateral resolutions were evaluated at 2μm and 4.4μm, respectively. The three dimensional OCT images of dried fin of small fish were measured. The basic technique of an ultrathin low invasive imaging probe has been developed.
