| abstract | PURPOSE:To measure transmission characteristics with good reproducibility by calculating the difference between projection light from a pinhole when the diameter of the pinhole is (r) and that when (r+DELTAr) while rotatig a turntable, and obtaining a far visual field image. CONSTITUTION:The calculation of the far visual field image (FEP) of light projected frm an annular fine part 4 of a graded type optical fiber 1 between the radii (r) and (r+DELTAr) of the core 2 is carried out on the basis of the difference between the projection light when the diameter of the pinhole 6 is (r) and that when (r+DELTAr). Then, this is measured and computed while the turntable 7 is rotated successively to obtain FEP11. Then, such a mode scrambler that FEP11 of the annular fine part with constant width is equal is used. Consequently, the reproducibility of measurements of transmission band width and light loss is obtained. |
