Abstract
We present time-domain transmission imaging of an opaque structure in pork- fat tissue obtained with a terahertz (THz) field sampling technique. Compar ed with imaging with near-infrared pulses, the terahertz sampling technique shows significantly enhanced contrast, as a result of low scattering. For enhanced spatial resolution, we show mid-infrared THz imaging of onion cell s. Water absorption of THz pulse in muscle tissues is discussed.
