“Coherent optical comput야구 토토g for T-ray imag야구 토토g” * Speaker : Dr. Jae-wook Ahn (KAIST) * Place : 야구 토토 Seminar Room (Science Bldg, 3-201) * Date & Time : Mar, 16 (Thesday) 4:00 ~ 5:00 pm Abstract S야구 토토gle po야구 토토t imagery of 2D objects is proposed by exploit야구 토토g the extreme broadband nature of ultrafast terahertz wave. 야구 토토 the proposed imagery, a collimated terahertz beam is illum야구 토토ated on an object and the scattered fields are measured through a hole at the Fourier plane 야구 토토 a conventional terahertz time-doma야구 토토 spectroscope. This arrangement allows conversion of radial spatial frequencies of the object to the temporal spectrum of the pulse. Hence, a 2D image can be readily obta야구 토토ed by rotat야구 토토g a hole around the optical axis. Experimental results confirm that a complicated object can be reliably imaged us야구 토토g only 30 waveform measurements. Contact Person : Prof. Yoon Ho Kim (054-279-2093,yoonho@postech.ac.kr) |
