| Summary: | 碩士 === 國立交通大學 === 照明與能源光電研究所 === 106 === In this study, an external magnetic field was utilized to drive a fiber optic scanning device coated with magnetic thin film. The magnetic film is made of nickel (Ni) by radio-frequency sputtering equipment, which is repeatable, consistent, and highly uniform in thickness. The length of coating is 3 cm; the thickness is 17 micrometers. Specifically, for the scanner length of 6 cm, 5 cm and 4 cm, the static and dynamic characterization of the scanning device were carried out, analyzed, and applied to acquiring line-scans upon some fluorescent targets. As a result, it was found that the scanning width at frequencies other than the vicinity of the resonant frequencies, was too small for any practical imaging application. For a fixed length of 6 cm, the resonant frequency of the fiber is 38.4 Hz and the scan range can reach 1.28 mm, which is applied to 1D scanning on the strip patterns on a resolution target atop a fluorescent plate and the blood vessels of zebrafish larvae injected with fluorescent dye, and compared with standard calibration.
