Terahertz time-domain spectroscopy (THz-TDS) is an useful method to investigate the optical characters of the matters in THZ range, and it can provide the information of the phase and amplitude of the electrical field when THz wave passes the sample. We measure the two liquid crystals PAA and MBBA by using THz-TDS. It shows that the birefringence of MBBA is between 0.080 ~ 0.127, and there is no apparent absorption spectrum between 0.2 ~ 1.6THz. It shows that the birefringence of PAA at 118℃ is about 0.06, and there is no apparent absorption spectrum between 0.2 ~ 1.2THz. 趙如蘋 2009 學位論文 ; thesis 85 zh-TW |
