Abstract

The numerous problems involved in making a hologram of a moving object are well known. Chief among them is the lack of coherence be-tween the reference wave and the light scattered from the moving object. This incoherence arises because the scattered light suffers a Doppler frequency shift due to the motion of the scattering object. At optical frequencies, this shift is so great that no available detector can perceive interference between object and reference waves, and hence they are effectively incoherent.
