Imaging an object out of the line of sight: (a) the sketch of ‘looking around a corner’ setup. A rough aluminum plate was illuminated with reference and object lights. The speckle pattern created by the light scattered from the aluminum plate was detected by a CCD image sensor at the position that avoided specularly reflected light. (b) The object hidden around the corner, (c) a part of the recoded speckle pattern, (d) the auto-covariance of the speckle intensity and (e) the reconstructed object image. The scale bars in b, c are 150 and 447 μm (60 pixels), respectively.
