Revealing of Axial Separation between Diffusers through Lateral Speckle Correlation

Not Accessible

Your library or personal account may give you access

Abstract

We experimentally demonstrate that the intensity correlation of speckled speckles before and after the lateral displacement of the concealed scatterer discloses the axial separation though speckle size, decorrelation length and speckle gearing. We expect to apply this technique into tracking objects hidden in the diffuse layer, measuring biological activity in diffuse layer etc.
