Abstract :
Advances in semiconductor materials and NIR ultrafast lasers have made it possible to generate and detect broadband electromagnetic pulses with frequencies ranging from 0.1 to over 3 THz (1 THz = 1012 Hz). We present recent work using these THz pulses to image exposed breast cancer and spectroscopic results that indicate differences in the properties of normal and tumourous skin tissue.
