Abstract :
We propose a method for depth-resolved imaging and relative-velocity sensing of moving objects hidden by turbid media using low-coherence interferometry combined with the speckle subtraction. Experimental results show that the method is useful for imaging objects hidden by the Intralipid or a diffuse plate in a depth-resolved manner and estimating the relative velocity.
