Terahertz Sensing for Biomedical Applications: A Dream or A Daydream

With the development of laser、 semiconductor and fine processing and material science, terahertz (THz) technologies has gained obvious improvement since this century. Biomedical applications are generally quite attractive. In this paper, I will try to give a fair evaluation of current THz sensing regarding biomedical applications. Moreover, some on-going work in our lab will be introduced, especially for imaging.
