Description
Summary:碩士 === 國立交通大學 === 照明與能源光電研究所 === 102 === In this paper, we use the higher-order-harmonic modulations of mode-locked laser pulses to offer multiple modulation frequencies for Frequency Domain Photon Migration (FDPM) System. Combined with a demodulation circuit, we demonstrate a GHz FDPM system, which breaks the bandwidth limitation of modulated source. In addition,for future clinical applications, we build a portable mode- locked Yb-fiber laser.
