Abstract

An imaging method using the Doppler effect is proposed in this paper. An object is illuminated by a sinusoidal wave from a linearly moving transducer. The frequency components of the reflected wave can be considered to be projections along lines at specified corresponding angles from the transducer. One can reconstruct images by applying conventional CT (computerized tomography) algorithms to the projections thus obtained. The theory is derived for coherent and incoherent processing. Theoretical results are confirmed by numerical simulations. Experimental results show that coherent Doppler tomography is much higher in resolution but more noisy than incoherent Doppler tomography.
