Image holography through convective fog

Light experiences a Doppler frequency shift if it is deflected by scattering on a moving particle. In holography that situation occurs when the light on the way from the object to the hologram passes through moving fog. Due to the Doppler shift the scattered light cannot interfere with the undisturbed reference wave. Hence only the unscattered portion of the object wave contributes to the interference fringes on the hologram. Therefore the reconstructed image is not blurred due to scattering in the fog. We present a simple theory of holographic vision through fog and some verifying experiments.
