Abstract :
Summary form only given. Application of a far-infrared pulse in the terahertz (THz) frequency range provides an advantage in imaging of chemical and biological materials due to strong molecular resonance in the frequency range. Two dimensional frame imaging of THz illumination is also possible as demonstrated recently. In this paper we report on THz imaging with a high spatial and temporal resolution using a free-space electro-optic sampling technique in the mid-infrared frequency range. A spatial resolution of sub 70-/spl mu/m is achieved. Our technique allows us to demonstrate the time-resolved THz transillumination for imaging of biological cells.
