Based on a micron-sized photonic transmitter operating at room temperature, an improved signal-to-noise ratio with a reasonable spatial resolution can be achieved. Biomedical THz imaging was demonstrated with a dried seahorse and a fresh flower, which were hidden in plastic sample holders and were invisible. Tissue and water distributions of distinct regions of the bio-samples were clearly resolved, showing the high imaging contrasts of the demonstrated system. These results reveal the possibility to construct a high-sensitivity THz imaging system with less than 1-mW optical excitation.application/pdf147026 bytesapplication/pdfzh-TWFar-infraredmillimeter-wavephotonic transmittersubmillimeter waveterahertz (THz) wave imagingjournal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/200611150121697/1/2372.pdf
