Abstract
A method is proposed for depth-resolved imaging and relative-velocity sensing of moving objects hidden by turbid media using low-coherence interferometry combined with the speckle subtraction. Samples are illuminated by a collimated beam from a superluminescent diode and the speckle image is detected by a CCD camera. Experimental results confirm the ability of the proposed method for imaging and estimating the relative velocity of aluminum diffuse plates hidden by the Intralipid or a diffuse plate in a depth-resolved manner.
