要約(日本語): We demonstrated FF OCM using an ultrathin forward-imaging SMMF (Short multimode fiber) probe of 50 μm core diameter, 125 μm diameter, and 7.4 mm length, which is a typical graded-index multimode fiber for optical communications. The axial resolution was measured to be 2.20 μm, which is close to the calculated axial resolution of 2.06 μm. The lateral resolution was evaluated to be 4.38 μm using a test pattern. Contacting SMMF to the primary somatosensory cortex and the agranular insular cortex of ex vivo rat brain, OCM images of the brain were measured, and internal structure information could be obtained.
